Bundle up a fever and sweat it out

Health
Myth

Bundling blocks heat loss and can cause dangerous overheating in infants. Instead: fewer layers, fluids, and weight-based paracetamol or ibuprofen.

Introduce allergens like peanut early

Feeding
Evidence-based

Large studies (like LEAP) support early, consistent introduction of common allergens once solids are established — it significantly lowers allergy risk. Thin textures, small amounts.

Early walkers are smarter

Development
Myth

Walking anywhere between 9–18 months is normal; timing has no link to intelligence. What matters is steady progress across milestones.

Cravings reveal the baby’s sex

Pregnancy
Myth

Cravings come from hormonal shifts and have nothing to do with the baby’s sex — same for bump shape, nausea severity or skin changes.

Eating crab causes miscarriage

Pregnancy
Myth

No evidence links cooked crab to miscarriage. The real seafood rules in pregnancy are avoiding raw/undercooked items and high-mercury fish — well-cooked low-mercury seafood is beneficial.

You must give up your cat when pregnant

Pregnancy
Partly true

Toxoplasmosis risk comes mainly from litter boxes and raw meat, not from petting your cat. Delegate litter duty (or wear gloves and wash hands), and there’s no need to rehome.

No coffee at all during pregnancy

Pregnancy
Partly true

Major guidelines accept up to 200mg caffeine daily in pregnancy (roughly one 12oz coffee). Count the hidden caffeine in tea drinks, cola and chocolate too.

Pregnant women can’t fly

Pregnancy
Myth

Uncomplicated pregnancies can generally fly safely before 36 weeks (airlines set their own cut-offs). On long flights, hydrate and move your legs regularly.

A pointy bump means a boy

Pregnancy
Myth

Bump shape depends on the baby’s position, your build, abdominal muscles and fluid volume — not the baby’s sex.

No skincare or makeup during pregnancy

Pregnancy
Partly true

Basic moisturiser and sunscreen are safe. The actual avoid-list is short: retinoids, high-dose salicylic acid, hydroquinone and a few others — read labels rather than quitting everything.

Pregnancy means eating for two

Pregnancy
Myth

The first trimester needs almost no extra calories, and later trimesters only ~300–450 kcal more daily (a glass of milk plus an egg). Doubling portions mainly doubles gestational-diabetes risk.

Pregnancy means bed rest, not exercise

Pregnancy
Myth

Uncomplicated pregnancies benefit from 150 minutes of moderate weekly exercise (walking, swimming, prenatal yoga) — better glucose control, mood and labour outcomes. Follow medical advice for complications.

Babies arrive on their due date

Pregnancy
Myth

Only ~5% of babies arrive on the due date. Anywhere from 37–42 weeks is normal — the due date is the middle of a range, not a deadline.

Shaving a newborn’s hair makes it grow thicker

Daily Care
Myth

Hair follicle count and texture are genetic, fixed at birth. Shaving changes nothing — and razors can hurt delicate infant scalp.

Pinching the nose bridge makes it taller

Daily Care
Myth

Nose shape is genetic. Pinching does nothing except risk mucosal injury and ear infections.

Squeeze a newborn’s nipples to prevent inversion

Daily Care
Myth

Newborn breast swelling is a temporary effect of maternal hormones and resolves on its own. Squeezing risks infection and mastitis — never do it.

Binding legs makes them straight

Daily Care
Myth

Infant bow-legs are usually physiological and straighten with growth. Binding actually impedes hip development and raises the risk of hip dysplasia.

Sunbathing cures newborn jaundice

Daily Care
Partly true

Mild physiological jaundice clears through feeding and excretion; window sunlight is inefficient and risks sunburn. If bilirubin hits treatment thresholds, proper phototherapy is what works.

A bald patch on the back of the head means calcium deficiency

Daily Care
Myth

The bald patch is friction from lying down and regrows once baby sits up more. It’s not calcium deficiency — nor are sweating or night waking, usually.

Teething causes high fever

Daily Care
Myth

Teething can cause slight temperature rises and fussiness, but not true fever above 38.5°C. Treat high fever as illness — don’t let "teething" delay spotting a real infection.

Baby walkers help babies walk sooner

Daily Care
Myth

Research shows walkers actually delay motor development and cause serious falls and burns — Canada has banned them. The best walking equipment is floor time and bare feet.

Holding babies out to toilet early trains them faster

Daily Care
Myth

Toileting readiness follows neurological development, typically at 18–30 months. Early holding-out doesn’t accelerate it, and pressure can create stool withholding.

Fever itself damages the brain

Daily Care
Myth

Fever from common infections doesn’t injure the brain — encephalitis or meningitis themselves do. The goal of fever treatment is comfort, not brain protection.

Alcohol rubs and ice baths bring fever down fast

Daily Care
Myth

Alcohol absorbs through skin and can poison; ice baths trigger shivering that raises core temperature. Both are abandoned by guidelines — use paracetamol or ibuprofen instead.

Never touch or wash the soft spot

Daily Care
Myth

A tough membrane protects the fontanelle — normal washing and gentle touch are completely safe. Avoiding it just builds up cradle cap.

Colostrum is dirty and should be discarded

Feeding
Myth

Colostrum has the highest concentration of antibodies and immune factors — often called the baby’s "first vaccine." Not a drop should be wasted.

Breast milk loses its nutrition after 6 months

Feeding
Myth

Breast milk keeps its nutrients and antibodies. Solids start at 6 months because the baby’s needs grow (especially iron) — not because milk "goes off." WHO supports breastfeeding to 2 years and beyond.

Formula keeps babies fuller, so it’s more nutritious

Feeding
Myth

Slower digestion doesn’t mean better nutrition — just different gastric emptying. Easy digestibility is one of breast milk’s advantages. Both feeding methods raise healthy babies.

A mum with a cold must stop breastfeeding

Feeding
Myth

Keep breastfeeding through a cold — the antibodies in your milk protect the baby. Mask up, wash hands, and note that most common cold medicines have breastfeeding-safe options.

Bone broth is the best calcium source

Feeding
Myth

Bone calcium barely dissolves into broth — a bowl often has less calcium than half a cup of milk, plus plenty of fat. Real calcium sources: dairy, tofu, leafy greens.

Rice water is the most nourishing baby food

Feeding
Myth

Rice water is mostly water and starch — very low nutrient density that fills the stomach and crowds out milk and iron-rich foods. Weaning foods should be small-volume, high-density.

Fruit juice is healthy for babies

Feeding
Myth

Paediatric guidance says no juice before 12 months: high sugar, little fibre, bad for teeth and appetite. Whole fruit always beats juice.

Homemade rice cereal is safer than store-bought

Feeding
Partly true

Hygiene may be fine, but homemade cereal lacks fortified iron — the main job of first foods. If you make your own, pair it deliberately with red meat and liver.

Babies need salt for strength

Feeding
Myth

Milk and natural foods already provide all the sodium infants need. Added salt before 12 months only burdens the kidneys and trains a salty palate.

Bovine colostrum and protein powder boost immunity

Feeding
Myth

No solid evidence supports these supplements for healthy children. The real immune boosters are vaccines, sleep, a balanced diet and outdoor play.

Rich, fatty soups boost milk supply

Feeding
Myth

Supply is driven by frequent effective sucking plus adequate fluids and calories. The fat in rich soups doesn’t make milk — it may raise clogged-duct risk. Any fluid works.

Egg yolk must be the first solid food

Feeding
Partly true

Egg yolk is fine early, but it’s not a mandatory first food, and its iron trails fortified cereal and red meat. The first-food keyword is "iron-rich" — the format is flexible.

Walnuts boost the brain because they look like one

Feeding
Myth

Shape-based nutrition has no scientific basis. Walnuts are fine nuts, but what actually builds brains: DHA (oily fish), iron, iodine — and rich interaction with you.

Tummy sleeping gives a rounder head, so it’s fine

Sleep
Myth

Back-sleeping for the first year is the iron rule — tummy sleeping sharply raises SIDS risk. Fix head shape with supervised awake tummy time and position changes instead.

Shaping pillows prevent flat head

Sleep
Myth

No pillow belongs in a cot before age one — shaping pillows don’t work and are a suffocation hazard. Prevent flat spots by alternating head position and awake tummy time.

Skipping naps means better nights

Sleep
Myth

For babies it’s the opposite: overtiredness raises stress hormones, making settling harder and nights worse. Good naps are the foundation of good nights.

Rocking or feeding to sleep is a bad habit to break immediately

Sleep
Partly true

Needing soothing to sleep is normal in the early months, not spoiling. It only needs gradual change if it’s degrading the whole family’s sleep — on your timeline, not anyone else’s.

A snoring baby is a soundly sleeping baby

Sleep
Myth

Persistent snoring isn’t deep sleep — it can signal enlarged adenoids/tonsils or sleep-disordered breathing, which affects development. Worth a medical review.

Night feeds must end by a set age

Sleep
Myth

There’s no universal night-weaning deadline. Most babies *can* go without night feeds after 6 months, but "can" isn’t "must" — decide by growth and family needs.

White noise is addictive and damages hearing

Sleep
Partly true

Used sensibly it’s safe: ~50 dB (shower volume), machine a metre-plus from the cot. The "dependence" is a reversible association — no different from adults preferring quiet.

Colds come from being cold

Health
Myth

Colds are caused by viruses, not low temperature. Winter colds spike because of indoor crowding. Overdressing just overheats the baby.

Colds need antibiotics

Health
Myth

Colds are viral; antibiotics only work on bacteria. Misuse doesn’t shorten illness and drives resistance and gut damage. Leave the antibiotic call to the doctor.

Coughing long enough turns into pneumonia

Health
Myth

The causality is backwards: pneumonia causes coughing, not the reverse. Coughing is protective airway clearing. Watch instead for fast breathing, retractions and lethargy.

Vaccines cause autism

Health
Myth

This claim traces to a fraudulent, retracted paper whose author lost his licence. Large studies covering millions of children since have found no link whatsoever.

Multiple vaccines at once overload the immune system

Health
Myth

A baby’s immune system handles vast antigen loads daily; combined vaccines add a drop in that ocean. Co-administration is rigorously tested — and saves clinic trips.

Eczema comes from internal "dampness"

Health
Myth

Eczema is a damaged skin barrier plus immune factors — its enemy is dryness, not moisture. Treatment is generous moisturising and topical medication when needed.

Babies don’t need vitamin D drops — sunshine is enough

Health
Partly true

In theory yes, but infant skin shouldn’t be sun-exposed and sunscreen blocks synthesis — in practice babies rarely get enough. Standard advice: 400IU vitamin D daily.

Imported medicines bought online are safer

Health
Myth

Grey-import medicines mean unreadable labels, unfamiliar dosing units and no regulatory recourse. Safe dosing requires labels you understand and a supply chain you trust.

Fever medicines damage the liver and kidneys — avoid them

Health
Myth

Weight-dosed paracetamol and ibuprofen have excellent safety records. Harm comes from overdosing and stacking multi-ingredient cold remedies. If your child is miserable, treat.

Green snot means bacterial infection needing antibiotics

Health
Myth

Snot turning thick and green is the natural course of a cold (immune-cell debris), not proof of bacteria. What matters: symptoms beyond ~10 days without improving, or persistent high fever.

Colic needs gripe water or probiotics to resolve

Health
Myth

Colic self-resolves by 3–4 months as the nervous system matures. Miracle remedies have weak evidence, and some contain sugar or alcohol. Soothing techniques plus time are the real fix.

Late talkers are secretly gifted

Development
Myth

This saying has delayed help for too many children. Clear language delays (no words at 18 months, no two-word phrases at 2) warrant early assessment — early intervention beats waiting.

Left-handedness should be corrected early

Development
Myth

Hand preference is wired in the brain. Forced switching brings no benefit and can cause frustration and speech issues. Left-handedness is not a defect.

The earlier the enrichment classes, the smarter the child

Development
Partly true

Early brain growth runs on high-quality interaction, not on classes as a format. Daily conversation, shared reading and free play deliver the same stimulation — classes are optional.

The first-birthday grabbing ritual predicts a career

Development
Myth

A lovely tradition — but what a one-year-old grabs depends on colour, distance and novelty, not destiny. Enjoy the photos; skip the fortune-telling.

Skipping crawling and walking straight away means advanced development

Development
Partly true

Some children skip crawling and develop fine — but walking early isn’t superiority. Crawling still benefits coordination and is worth encouraging; assess if other milestones lag too.

Baby talk ("din-dins") delays language

Development
Partly true

Distinguish two things: melodic, exaggerated "parentese" demonstrably helps language learning. What should fade over time is using only duplicated toddler words without full sentences.

Flashcards unlock the right brain and create prodigies

Development
Myth

Left-brain/right-brain training is a pop myth rejected by neuroscience. Young children learn from real interaction and play; rote flashcard memory doesn’t transfer to real intelligence.

Phone and computer radiation harms the fetus

Pregnancy
Myth

Phones, computers and Wi-Fi emit non-ionising radiation — far too weak to damage DNA, and unrelated to birth defects. Anti-radiation garments have no credible evidence. Ionising radiation (X-rays) is the real concern: just tell the technician you’re pregnant.

Sex during pregnancy hurts the baby

Pregnancy
Myth

Sex is safe in uncomplicated pregnancies — amniotic fluid, the uterine muscle and the cervical mucus plug protect the baby. Abstain only on medical advice for placenta praevia, unexplained bleeding, cervical insufficiency or preterm labour signs.

Epidurals cause chronic back pain and lower the child’s IQ

Pregnancy
Myth

Controlled studies find no link between epidurals and long-term back pain — postpartum backache comes mostly from posture changes, ligament laxity and carrying a baby. Nor is there evidence epidurals affect a child’s cognitive development. A few days of tenderness at the site is normal.

Never dye or perm your hair while pregnant

Pregnancy
Partly true

Very little modern hair dye is absorbed through the scalp, and there’s no evidence of birth defects. Most guidance says "be cautious, not abstinent": wait past the first trimester, ventilate the room, and limit scalp contact. Highlights that avoid the roots are an easy compromise.

The more calcium in pregnancy, the better the baby’s bones

Pregnancy
Myth

Calcium beyond requirement doesn’t build better bones — it can cause constipation, raise kidney-stone risk and interfere with iron and zinc absorption. Supplement as advised, and prioritise food sources (dairy, tofu, dark greens).

Waters breaking means an immediate C-section

Pregnancy
Myth

Waters breaking signals labour starting — it is not an indication for surgery. At term, most people go into labour naturally or are induced after assessment, with monitoring for infection and fetal wellbeing. Note the time, colour and smell and go in promptly — but surgery is not the default.

No bathing, hair-washing or open windows during the postpartum month

Pregnancy
Myth

These taboos come from an era without reliable heating or hot water. Today, staying clean actually lowers the risk of wound and breast infection. The rule is warm water, quick washes, no chill, and care around wounds. Rooms need ventilation — overheating carries its own risks.

Epstein pearls and buccal fat pads should be lanced

Daily Care
Myth

⚠️ Never lance them. The white spots on the gums (Epstein pearls) and the cheek fat pads are normal structures that resolve on their own — the fat pads are essential for sucking. Piercing them risks serious oral infection and sepsis.

Holding your baby too much spoils them

Daily Care
Myth

You cannot spoil an infant with responsiveness in the first year. Responding promptly to cries and the need for contact builds secure attachment — and research shows those children grow up more independent, with better emotional regulation, not less.

Let them cry until they stop — the "cry-it-out immunity" method

Daily Care
Myth

This century-old behaviourist extreme is rejected by mainstream child development: after prolonged non-response, a baby who finally quiets has usually given up signalling, not learned self-soothing. Distinguish it from graduated methods for babies over 6 months with a set routine and timed parental check-ins — those are research-supported and don’t harm attachment.

Babies shouldn’t be in air conditioning

Daily Care
Myth

Overheating is a known SIDS risk factor — bundling is far more dangerous than air conditioning. Sensible practice: 24–26°C, no direct draft on the baby, regular ventilation, and attention to hydration. So-called "air-con sickness" is dryness and temperature swings, not the appliance.

Don’t cut a baby’s nails in the first year

Daily Care
Myth

Newborn nails grow fast and will scratch their own face and eyes. Use baby nail scissors with rounded tips, trim along the fingertip curve while they sleep, and don’t cut too deep. Nails are routine care, not superstition.

Clean out your baby’s earwax regularly

Daily Care
Myth

Earwax migrates out on its own with chewing and skin turnover, and it’s protective and antibacterial. Cotton buds push it deeper and can scratch the canal or perforate the eardrum. Wipe only the outer ear; leave suspected impaction to a doctor.

Potato slices or cooling patches bring down a fever

Daily Care
Myth

These provide brief local skin cooling but don’t shift the body’s temperature set point, so they barely affect fever. When a child is uncomfortable, weight-dosed paracetamol or ibuprofen is what works — alongside fluids and rest.

A newborn girl’s pseudo-menstruation is a problem needing treatment

Daily Care
Myth

A small amount of blood-tinged vaginal discharge in the first days is a normal withdrawal response to maternal oestrogen, usually resolving in 2–7 days. Just clean normally — no intervention needed. Seek review if bleeding is heavy, prolonged, or comes with fever.

Watery-looking breast milk has no nutrition

Feeding
Myth

Milk composition shifts within a single feed: the early milk is thirst-quenching and watery, the later milk is markedly higher in fat and calories. Colour tells you nothing about nutrition. Judge intake by nappies, growth curve and demeanour.

Milk produced while angry is toxic

Feeding
Myth

Emotions don’t make milk toxic. Strong stress can briefly slow the let-down reflex via stress hormones, but the milk itself remains safe. What deserves attention is supporting the mother — not discarding milk.

Babies need extra water before 6 months

Feeding
Myth

Breast milk and formula are about 87% water — that fully covers a baby’s needs. Extra water fills a tiny stomach, displaces milk, and in volume can cause water intoxication (hyponatraemia). Small sips with meals are fine once solids start at 6 months.

Clogged ducts need forceful, painful massage

Feeding
Myth

Aggressive massage causes tissue oedema and injury, often worsening the blockage and sometimes triggering mastitis. Current guidance: frequent effective milk removal, brief warmth before feeding, cold compresses after, and gentle lymphatic-style stroking. See a doctor for persistent fever or spreading redness.

Babies can’t digest meat before age one

Feeding
Myth

The opposite is true: red meat is among the most important iron-rich first foods, recommended from 6 months. Iron stores from pregnancy run low after 6 months, and a diet of only porridge and vegetables is a common route to iron-deficiency anaemia.

A hard pillow (books, rice bags) shapes a nicer head

Sleep
Myth

Ineffective and dangerous: nothing — pillows or soft items — belongs in a cot in the first year, all are suffocation hazards, and hard objects can cause pressure injury. The real fix is supervised tummy time and alternating head position; severe flattening warrants paediatric review.

Vigorous shaking settles a baby faster

Sleep
Myth

⚠️ A lethal misconception. With weak neck muscles and a proportionally heavy head, violent shaking tears blood vessels in the brain — shaken baby syndrome causes permanent injury and death. Gentle rocking and walking while holding are safe; anything with a whipping motion must stop. When overwhelmed, put the baby down safely and leave the room for a few minutes.

No bathing for 24 hours after vaccination

Health
Myth

Bathing doesn’t affect vaccine efficacy or cause infection. The only precautions: don’t rub the injection site, and keep it clean and dry afterwards. What actually matters is the 30-minute observation for acute reactions and monitoring for fever after.

Multi-symptom cold medicines help children recover faster

Health
Myth

Multiple regulators advise against over-the-counter multi-symptom cold medicines under age 4: weak efficacy evidence, and their combined ingredients easily double up with fever medicine into an overdose. Cold care is fluids, rest, single-ingredient antipyretics when needed, and saline drops for congestion.

Probiotics cure everything and should be taken routinely

Health
Myth

Probiotic effects are highly strain- and condition-specific: certain strains have evidence for antibiotic-associated and acute infectious diarrhoea — which doesn’t generalise to constipation, eczema, immunity or appetite. Healthy children don’t need routine supplementation; a varied diet is the foundation of gut flora.

Late teething means calcium deficiency

Health
Myth

A first tooth anywhere between 4 and 14 months is normal and largely genetic — not a calcium issue. If growth is on track and vitamin D is supplemented, there’s nothing to fix. No teeth by 15–18 months is worth a paediatric or dental review.

Playing Mozart to your bump raises the baby’s IQ

Development
Myth

The "Mozart effect" came from a small study of adults showing a brief spatial-reasoning bump; larger replications failed, and it was never shown to affect fetal intelligence. Play music by all means — relaxation and connection matter — just don’t treat it as an IQ investment, and keep speakers off the bump.

Boys just talk later — no need to worry

Development
Partly true

Boys do average slightly later language development — but the gap is small and nowhere near enough to explain a clear delay. "Boys talk late" is one of the most common reasons help gets postponed. The red flags apply regardless of sex: no words at 18 months, no two-word phrases at 2, or any loss of language.

The earlier you teach reading, the smarter and better-prepared the child

Development
Myth

Early decoding advantages typically wash out by mid-primary school, with no reliable evidence of long-term benefit. What actually predicts later reading is oral vocabulary, phonological awareness and enjoyment of shared books. Swapping play and conversation for drills can damage the motivation to read.
