35 Weeks

Your baby is getting plump. The fat deposits are now beginning to offer form and fullness to your baby's legs and arms. Your baby is taking up most of the room in your uterus, so there is a lot less room to move around. Also, your baby's lungs are now completely developed and producing what is called surfactant, a substance that helps in the exchange of oxygen in the lungs. Your baby doesn't have much room to maneuver now that she's over 18 inches long and tips the scales at 5 1/4 pounds (pick up a honeydew melon). Because it's so snug in your womb, she isn't likely to be doing somersaults anymore, but the number of times she kicks should remain about the same. Her kidneys are fully developed now, and her liver can process some waste products. Most of her basic physical development is now complete — she'll spend the next few weeks putting on weight.
