Week 12: about the size of a plum

The Week of Small Reflexes — Week 12

5.4 cm14 gTrimester 1
Your baby says

This week my fingers may sometimes curl up on their own. Whether I'm the one doing it is another question.

What may be happening this week

Around these weeks, first reflexes such as fingers opening and closing or sucking-like movements may begin to appear. These movements usually can't be felt from the outside yet.

A note for you

For the mother, this week may come with mixed feelings as the end of the first trimester approaches. For the father or partner, coming along to ultrasound or checkup days can be a simple way of being part of it.

Small curls, a small week. Let this note stay short too.

Sizes are averages and every baby grows at their own pace. This page is general information, not medical advice.
