They are asleep!!

While I was working out, Rex stayed with Zack. I guess he was sitting on the floor watching Dora, with his legs under him. He went to stand up and his legs were asleep. Rex said that he kept pointing to his legs and saying "oh". I don't remember another time where I have seen him do this, so it must have been his first experience with his legs falling asleep. I guess he was wobbly and walked over to Rex and sat on her lap for a while.
