Weeks 33

Oct 31 – Nov 06

 33 weeks: Your baby is about the size of a pineapple

Measuring 17-plus inches from head to heel and weighing a little over 4 pounds, your baby is rapidly losing that wrinkled, alien look and his skeleton is hardening.

Baby's bones continue to harden and his lungs are almost fully developed as the lanugo starts to disappear. While the rest of the bones become hard, the skull bones will remain soft to enable natural birth. The soft spot will remain for a few years yet, in order to accommodate the growing brain.
