Frustration can be part of learning

Moments of frustration often appear when babies are close to a new ability

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

Around week twenty, you may notice your baby grunting, fussing or getting cross during play. These moments of frustration often appear when something new is almost within reach.

What is happening

Your baby is trying to do things their body cannot quite manage yet. Reaching a toy, rolling over or holding a position can feel just out of grasp. The frustration you see is the gap between what they want to do and what they can do, and that gap is where learning happens.

Is this normal

Yes. Short bursts of frustration during play are common at this age and not a sign that anything is wrong. Babies who get a little cross while trying are often very close to a new step.

What you may notice

What helps right now

What to expect next

Over the next few weeks, the effort usually pays off. Reaching becomes easier, rolling more confident, and the cross moments fade as the new skill clicks into place. Each one tends to pass as quietly as it arrived.
