"Your baby's skeleton is changing from soft cartilage to bone, and the umbilical cord — her lifeline to the placenta — is growing stronger and thicker. Your baby weighs 5 ounces now (about as much as a turnip), and she's around 5 inches long from head to bottom. She can move her joints, and her sweat glands are starting to develop."
But don't be fooled by the "her"...we haven't found out yet if it's a boy or girl. Only 17 more days until we do! I can't wait!
