At 33 weeks your baby is more than 17 inches from head to toe, and weighs a little over 4.2 pounds(about the size of a pineapple).
Your baby is rapidly losing that wrinkled, alien look and it's skeleton is hardening. The bones in it's skull aren't fused together, which allows them to move and slightly overlap, making it easier for it to fit through the birth canal. Your baby can see(and taste) it's liquid environment, hear your heartbeat and voice, and feel the sensation of grabbing it's own toes.
Note: Every baby develops a little differently — even in the womb. This information is to give you a general idea of your baby's size.
