What is a wake window?

A wake window is the amount of time a baby can comfortably stay awake between sleeps before becoming overtired. For newborns (0-6 weeks), wake windows are just 45-60 minutes — including feeding time. By 3 months this stretches to 75-90 minutes.

The single most common newborn sleep mistake: keeping baby awake too long, thinking it will help them sleep better at night. It almost always makes things worse.

The EASY Routine

EASY — Eat, Activity, Sleep, Your time — is one of the most practical frameworks for the early months. Feed on waking, short awake period, then down for a nap before overtiredness sets in.

Safe sleep non-negotiables

Always place baby on their back to sleep
Firm, flat, waterproof mattress in their own sleep space
No loose bedding, pillows or bumpers
Room temperature 16-20°C
Room-sharing for the first 6 months

💡 Key takeaway: Respect the wake window, prioritise safe sleep, and remember newborn sleep chaos is temporary. Most babies consolidate sleep between 3-6 months as their neurology matures.

💬 Parents also asked

How do I know if my baby is overtired? +

Watch for these cues: rubbing eyes, yawning, staring into space, or becoming fussy and harder to settle. Acting on these cues quickly -- before the meltdown -- is the key. An overtired baby produces cortisol, which actually makes it harder for them to fall asleep.

Is it safe for my baby to sleep on their side? +

No -- until your baby can roll independently, they should always be placed on their back to sleep. This is the safest position and reduces SIDS risk. Once they can roll both ways themselves, you don't need to reposition them.

When will my baby sleep through the night? +

Most babies start sleeping longer stretches between 3-6 months as their nervous system matures -- but "sleeping through" often means 5-6 hours, not necessarily 12. It varies hugely between babies, and night wakings are completely normal well into the first year.
