Skull flexibility

The bones in your baby's skull aren't fused together, which allows them to move and slightly overlap, making it easier for her to fit through the birth canal. (The pressure on the head during birth is so intense that many babies are born with a cone-head-like appearance.) These bones don't entirely fuse until early adulthood, so they can grow as the brain and other tissue expands during infancy and childhood.

Your baby is rapidly losing that wrinkled, alien look, and her skin is less red and transparent. It's becoming soft and smooth as she plumps up in preparation for birth.

Lots of movement

It's getting snug in your womb, so your baby isn't doing as many somersaults, but the amount of kicking should remain about the same.
