What happens during week 41? For a full-term baby who is still inside your womb, is there anything else left to develop?

Functionally, your baby is quite ready even weeks before. The lungs are now independently capable of breathing, the immune system is now packed with enough antibodies to face the outside world, and the digestive system is ready to digest breast milk.

Still, your baby is a growing human - whether you give birth this week or not! Expect your baby to pack on more pounds, as extra fat grows underneath that supple skin. The lanugo and vernix should have completely disappeared by now.
