Your baby’s skeleton is mostly rubbery cartilage, but will start to harden as the weeks go by. A protective substance called myelin slowly begins to wrap around his spinal cord. Sweat glands are starting to develop all over his body. Just as he grows bigger, the umbilical cord, his lifeline to the placenta, is growing stronger and thicker, too.
