Naps begin changing before night sleep does

Why daytime sleep often shifts first

The Millie's Team By The Millie's Team · Parenting Notes

Around week nine, daytime sleep often shifts first as rhythms develop. Shorter or differently timed naps can be part of progress rather than disruption.

What is happening

Your baby's sleep is starting to mature. The deep, all in one sleep of the newborn weeks is gradually being replaced by sleep that has more distinct cycles. Naps are usually the first place this shows up, often becoming shorter or moving around in the day.

Is this normal

Yes. Many parents notice naps becoming less predictable just as night sleep starts to feel a little more settled. Some babies take several short naps. Others surprise everyone with one long one. Both are normal at this age.

What to expect next

Over the coming weeks and months, naps will gradually start to organise into a looser daytime shape. There is no need to push for a strict schedule yet. The changes you are seeing now are part of how sleep matures, and the patterns will slowly become clearer on their own.
