33 Week Update

This week your baby weighs a little over 4 pounds (heft a pineapple) and has passed the 17-inch mark. He's/she's rapidly losing that wrinkled, alien look and the skeleton is hardening. The bones in the skull aren't fused together, which allows them to move and slightly overlap, thus making it easier for the baby to fit through the birth canal. These bones don't entirely fuse until early adulthood, so they can grow as his/her brain and other tissue expands during infancy and childhood.
