29 Weeks

Things happening this week: Monkey is hardening his skeleton, which takes lots of calcium. His head is growing bigger as his brain is really filling out. His bone marrow is now completely responsible for his red blood cell production and he's starting to regulate his own temperature. His eyes can move in their sockets and he is increasingly responsive to outside stimuli like light and sound. When he's not busy preparing for his second appearance on stage in a few weeks, he is working very hard at packing on the pounds and working out. At just over 2.5 pounds, he measures more than 15 inches long.
