Sock gloves?

Ok, so Sean has a new "thing" and we are not sure where it came from, but is pretty funny. A couple of weeks ago, he started wearing one red sock on his hand and he did not want us to take it off. It started at night, when we found him sleeping with one sock on his hand and then carried over to the daytime hours. Then it expanded to just any sock, or some of mom's socks. We we don't know why he does this (he is not pretending it is a puppet) and for a few days he won't wear a sock and then all of the sudden he is wearing them again. Well the other night, we went to check on him like we always do and found him with not one sock on, but two and couldn't pass up the opportunity to capture the picture. We had to hold our laughter in so we wouldn't wake him.
