Cooper goes to David's room when Jesse and I go to work. Jesse lets Cooper in David's room and closes the door and David goes back to sleep for a while. According to David, Cooper and Sam have been a bit more brave in their socialization while David sleeps.
Yesterday morning when David woke up, he saw Cooper and Sam about one inch from touching 'nose to nose'. When he reached for his phone to take a picture, Cooper moved away from Sam and wouldn't allow him near again. The closest he was able to convince them to get was about five inches apart. This picture is of them just after they were five inches apart. I can't wait to see if Cooper will let Sam touch him.
Once that happens, I think there will be a really good friendship between them. I'll keep you posted!
