Pregnancy by week

At week 34, your baby’s bones are hardening. But the bones in his skull will remain flexible to help ease his passage through the birth canal.

At 35 weeks, your baby’s hearing is fully developed, her lungs are nearly mature, and her nervous system is continuing to develop.

The amount of amniotic fluid surrounding your baby will reach its peak at 36 weeks.

In some pregnancies, the baby is lying head down with her head facing toward the front of the mother's body. This is called “posterior presentation."

At 38 weeks, most of the lanugo (fine, downy hair) that covered your baby's body is gone, along with the vernix caseosa (whitish protective coating).
