Sneaky Jackson

Jackson usually likes to stay with me wherever I am. It's kind of unusual for him to be away from me for very long. Recently though, he's started to go in his room by himself, usually to get his blanket, but he doesn't come back quickly. I don't care if he plays by himself in his room. I actually think it's good for him to learn how to entertain himself. But recently when he goes into his room and is very quiet. Even when I'm in the room next to him I don't hear anything. When he does come find me or I go find him to see what he's doing this is what I've been finding:
Jackson with his binky. The rule in our house is that Jackson can have his binky when it's nap time or bed time. He loves going to bed because he gets his binkies. He has about 5 of them now. He usually throws most of them before he goes to sleep. When he gets up in the morning he throws his binkies in his crib. But he can usually still reach them. So he goes to his room, find one, and puts it in his mouth. Whenever I see him with one in he has a sneaky look on his face, like he's thinking "hahaha look what I have." Once when I went in there he was hiding behind the rocking chair in his room sucking on one. He's pretty sneaky.
