Our baby weighs about 5 ounces now, and is around 5 inches long — about the size of a large onion. The umbilical cord, the lifeline to the placenta, is growing stronger and thicker. Our baby can move his joints, and his skeleton — until now, rubbery cartilage — is starting to harden into bone. Some of it will remain cartilage for years after Little Mc's born. A newborn's skeleton has 300 parts (a combination of bone and cartilage). As our child grows, some of these parts harden and fuse together. By the time our baby reaches adulthood, he'll have just 206 bones.
