Sleep at 33 weeks
At 33 weeks, most babies are awake for 2.5 hours to 3.5 hours at a stretch and sleep 14–14 hours across the full day, over 2–2 naps plus nighttime sleep. The first wake window of the day is usually the shortest and the last one before bed the longest — the wake-window calculator spreads them out for you.

Week 33 questions
How long should a 33-week-old be awake between naps?
Most 33-week-olds handle about 2.5 hours to 3.5 hours awake at a time. Watch for sleepy cues — staring off, jerky movements, fussing — and start the nap routine a few minutes before the top of the window.
How much sleep does a 33-week-old need in 24 hours?
Typical total sleep at 33 weeks is about 14–14 hours in 24 hours, usually split into 2 naps plus nighttime sleep. A day or two outside that range is common and usually not a concern on its own.
How often should a 33-week-old eat?
Most 33-week-olds take about 4–6 milk feeds in 24 hours. Solids, once started, add to milk feeds rather than replacing them at this age. Steady wet diapers and weight gain matter more than hitting an exact number.
