Fussiness sometimes arrives before new skills

Why things can feel harder just before a change

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

Around week eleven, it can feel like things are getting harder just before something changes. Many parents notice this pattern repeating throughout the first year.

What is happening

When your baby is on the edge of a new skill, their brain is working hard in the background. Sleep can become lighter, feeds less settled, and moods more changeable. It is not a step back. It is the build up to something new.

Is this normal

Yes. Many babies have unsettled days or weeks just before a clear leap forward, such as more controlled hand movements, longer alert times, or new sounds. Some babies show this very obviously. Others barely show it at all.

What to expect next

These wobbly stretches usually settle within a week or two, often followed by something new and lovely to watch. The pattern of fussy phase, then leap, then calmer phase will repeat many times in the first year. Recognising it early can make it feel much less worrying when it comes around again.
