The Week Bones Firm Up — Week 15

10 cm70 gTrimester 2
Your baby says

This week I seem to be a bit sturdier. Going from soft to slightly less soft.

What may be happening this week

During this period, the skeleton continues to ossify, and bones may become more distinct over time. Ossification continues for a long time after birth as well.

A note for you

For the mother, it may feel good this week to notice the changes in her body at her own pace. For the father or partner, showing a little interest in these changes is a simple way to share this week.

A week of slowly getting sturdier. Let's keep the note plain too.

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