Baby Sleep Myths: Fact vs Fiction

If you've spent any time in a parenting group or scrolling social media at 3am, you'll know just how much conflicting advice is out there about baby sleep. Some of it is harmless. Some of it, if followed, could leave you chasing a solution to a problem that was never really there. Let's clear a few of the big ones up.

Myth: "Good babies" sleep through the night by three months

Fact: Every baby develops at their own pace. By three months, a baby's circadian rhythm has only just begun to establish itself, so waking overnight at this age, and often well beyond it, is normal.

Myth: Keeping your baby awake longer will help them sleep better at night

Fact: It feels logical, but it usually backfires. Overtiredness tends to lead to more frequent night waking, longer stretches of wakefulness and earlier mornings. Watching for tired cues and protecting age appropriate wake windows generally leads to smoother sleep.

Myth: Back sleeping increases the risk of choking

Fact: Placing your baby on their back to sleep, for every sleep, day and night, is the safest sleeping position and does not increase the risk of choking. This advice comes directly from The Lullaby Trust and is the foundation of safer sleep guidance in the UK.

Myth: A baby needs to learn to self-settle through crying it out

Fact: There is no single "right" way to help a baby learn to sleep. Responding to your baby with warmth while gradually building their confidence to settle is a legitimate and effective path, and choosing it doesn't mean you're setting your baby up to struggle later.

Myth: Feeding or rocking your baby to sleep is a bad habit you need to break

Fact: These are simply ways your baby has learned to feel safe and calm. Plenty of babies who are fed or rocked to sleep as young infants go on to sleep well as they grow. If it starts to feel unsustainable for you, that's a valid reason to make a change, not a sign something has gone wrong.

Myth: Swaddling is dangerous

Fact: Used correctly, swaddling for babies under around four to five months can genuinely help them settle and sleep for longer stretches. The key is doing it safely: hips loose enough to move, nothing covering the face, and stopping once your baby shows signs of rolling.

Myth: Babies should nap in total silence, or need total noise to sleep

Fact: Neither extreme is a rule. Some babies nap happily through household noise, while others are more easily disturbed. White noise can help mask sudden sounds, but it's worth working out what actually helps your own baby.
