What does the day of a 4 month old look like?

Four months is the first age at which a day with clock times makes sense. The internal clock has now developed, and with it a fixed plan starts to give support instead of frustration. So from this month, a daily schedule really starts to be useful.

The example day, hour by hour

This example schedule shows what a day can look like, not what it must look like. What stands out about this day: after every nap comes a full feed, and only then play. That's no coincidence but the order that keeps your baby from falling asleep at the breast or on the bottle.

Why there are four naps and not three

The wake window at this age is about two hours, and that's the maximum. Counting from 6:30, you end up with four blocks before bedtime. So the daily rhythm follows from the wake window, not the clock: how long your baby can stay awake in a row decides how many naps fit. The fourth nap is short on purpose: it bridges the late afternoon so your baby doesn't start the night overtired.

How long exactly your baby can stay awake is in the 4 month old wake window.

The stretch between three and seven

From 3:30 pm, what Kyra calls the three-hour rule begins: between three and seven you make the whole environment calmer, so less stimulation comes in. That's the preparation for the night, and it's the part of the day that's skipped most often. See the three-hour rule.

If the schedule suddenly stops working this month

Around four months, the sleep structure changes for good and your baby starts waking more often, at night too, two or three times. That's not your schedule breaking. See the four-month sleep regression.

How much your baby sleeps in total at this age is in how much a 4 month old sleeps.
