Your baby continues to put on weight by about 1/2 pound each week. It's no wonder the womb is becoming very cramped. Your baby is gaining weight quickly because layers of fat pile on and help in both body temperature regulation and developing her immunity in preparation for life in the outside world. You may find you are carrying your baby much lower now (or soon will be) as the baby drops into the birth canal, readying herself for birth. Your baby is about 19 inches long and weighs from 5.5 to 6.0 pounds.
She's shedding most of the downy covering of hair that covered her body as well as the vernix caseosa, the waxy substance that covered and protected her skin during her nine-month amniotic bath. Your baby swallows both of these substances, along with other secretions, resulting in a blackish mixture, called meconium, will form the contents of her first bowel movement.
At the end of this week, your baby will be considered full-term!
