How much sleep does a 4 month old need?

Four months is the age at which parents search the most, and that's no coincidence. A lot changes at once, and it feels like starting over.

This is roughly what belongs in this phase: the daily schedule, the number of naps and the night feeds. Guidelines, not law.

The balance

At night: 10 to 11 hours. You see longer and longer blocks, especially at the start of the evening. Some babies do six hours in a row, sometimes eight, but that varies a lot. Two or three night feeds is simply normal in this phase.

During the day: 4 to 5 hours, spread over three to four naps. If the naps are still very short, it becomes five.

Wake window: around two hours. That's the time your baby can handle before getting overtired. If the previous nap was only half an hour, your baby can stay awake less long and the next nap has to come sooner. If your baby slept 45 minutes or longer, those two hours are fine.

Why it feels messy right now

Four things come together.

The sleep cycle matures, which makes falling asleep harder and waking more frequent. That's the four-month sleep regression, and it has its own story: what happens then.

Your baby is in a growth spurt and wants to eat more, at night too.

Your baby becomes much more aware of the surroundings, and all that stimulation has to be processed at night. That costs energy.

And you recognize the phase by three words: cranky, clingy and crying.

Three things to steer by

1. Strengthen the rhythm. Start the day at a fixed time, even if your baby wakes at six one day and at nine the next. That builds the day and night rhythm. And choose an earlier bedtime rather than a later one: see moving bedtime earlier.

2. Keep the afternoon calm, and don't let the afternoon nap run too long. From around three, you wind down the stimulation (the three-hour rule). And don't let your baby sleep longer than three hours in a row during the day, because then too few calories come in during the day and they get made up at night.

3. Fill the feeding tank during the day. Actively offer feeds at the right moments, and feed in a quiet room if your baby gets distracted easily. See distracted while feeding.

What such a day can look like

An example, not a schedule to hold on to:

• 6:30 am wake up, change, cuddle, and a full feed
• then play, tummy time, practice rolling
• 8:15 am nap 1, until about half past nine, and on waking another full feed
• 11:15 am nap 2, until half past twelve, then feed again
• 2:15 pm nap 3, until about quarter past three, then feed
• 3:00 pm from here, stimulation goes down
• 5:00 pm a short bridging nap
• 6:30 pm last feed and the bedtime routine
• 7:00 pm bed

Look at the tired cues above all, not at these times. What you want is the order, not the clock.

And no, you're not teaching your baby anything wrong

The question that comes up most this month: won't I create bad habits if I feed and comfort extra now? No. Your baby can't regulate well yet in this phase and needs that support. Use what works, and wind it down step by step after the regression. See whether you can create bad habits.

The day itself, with clock times for every nap, is in the 4 month old sleep schedule.
