Week 39 and your baby is growing bigger than ever! In fact, at this point, your not-so-tiny human is now about the same weight as a small pumpkin.

During this week, the amount of fat under your baby’s skin will increase to regulate temperature after birth. This also contributes largely to your baby’s gradual weight gain.

Your baby is also beginning to form new skin cells, which will replace the older ones. Your baby’s skin may also take on a white-gray hue, but don’t worry about this minor change; color pigments won’t deposit on the skin until after birth anyway.

If you give birth this week, your baby should be healthy and all organs should be able to function without a support. If not, it’s okay! You can wait for a few more weeks before the grand welcome.
