Newborn sleep questions Practical, science-based guidance — no fluff.
How much sleep do newborns need?
14–17 hours per 24 hours, in short stretches of 2–4 hours. Quality is irregular and unpredictable for the first 6–8 weeks. This is biologically normal.
Why does my newborn have day/night confusion?
Circadian rhythm doesn’t develop until 8–12 weeks. Help it along: bright light + activity during the day, dim + quiet + boring at night. Avoid eye contact during night feeds.
Should I wake my newborn to feed?
Yes, every 2–3 hours during the day and at least every 4 hours at night, until baby regains birth weight (~2 weeks). After that, follow your pediatrician’s guidance.
Is swaddling safe?
Yes, until baby shows any sign of rolling — usually 2–3 months. Then transition to a sleep sack with arms free. Always swaddle for back-sleeping per AAP guidance.
When will my newborn sleep longer stretches?
The longest stretch typically grows to 4–6 hours by 6–8 weeks. See when baby sleeps through the night.
Do I need a sleep schedule yet?
No. Before 12 weeks, watch wake windows (see calculator) rather than the clock.
