Monster Update: 31

This week, the Tummy Monster measures over 16 inches long and weighs about 3.3 pounds (approx. weight of four navel oranges) and he is heading into a growth spurt! He can turn his head from side to side, and his arms, legs, and body are beginning to plump out as needed fat accumulates underneath his skin. He's moving a lot, too, so is having some trouble sleeping because the Monster's kicks and somersaults keep her up. Her ability to walk long distances or handle bumpy roads is significantly decreased, as well. But all this moving is a sign that your baby is active and healthy.
