33 weeks

The 33rd week of pregnancy and the four weeks that follow mark a time of astounding growth as your baby reaches her ultimate birth weight.

This week your baby weighs a little over 4- 4 1/2 pounds (heft a pineapple) and might grow a full inch in length this week alone! He has passed the 17-inch mark.Your baby continues to gain weight rapidly — about a half pound a week. He's rapidly losing that wrinkled, alien look and his skeleton is hardening. The bones in his skull aren't fused together, which allows them to move and slightly overlap, thus making it easier for him to fit through the birth canal. (The pressure on the head during birth is so intense that many babies are born with a conehead-like appearance.) These bones don't entirely fuse until early adulthood, so they can grow as his brain and other tissue expands during infancy and childhood. Te pupils of her eyes can now adjust to bright or dim light, just like yours.His lungs continue to develop.Your amniotic fluid has reached its maximum level now — there's simply no more room! With less fluid to cushion them, your baby's kicks might feel a bit uncomfortable.
