Teaching a newborn day from night
The first 8 weeks are not about schedules - they are about light, contrast and short windows.
Their clock is not built yet
Melatonin production does not begin to settle into a rhythm until roughly 8-12 weeks. Until then your newborn genuinely cannot tell 3am from 3pm, and no schedule will change that.
What you can do is give the body the signals it needs to build the rhythm.
Light is the lever
Daytime: bright, normal household noise, curtains open, feeds and play in the living room. Nighttime: dark, quiet, minimal eye contact, feeds in the nursery with a dim red or amber light.
That contrast, repeated for weeks, is what builds the circadian rhythm. It is slow and it works.
Keep the window short
At 0-4 weeks the wake window is 30-60 minutes. That includes the feed and the nappy change. If your newborn has been awake for 45 minutes, the next step is sleep - not tummy time.
Bright days, dark nights, 30-60 minute windows. The rhythm comes around 8-12 weeks.
Guidance only, not medical advice. Every baby is different — adjust to your baby's cues and talk to your pediatrician about any sleep concern.
