I Found My Thumb

So far Jude has enjoyed his pacifier.  From only a few days old he has taken it easily and we've used it to sooth him.  Just recently he has discovered his hands and has shown a lot of interest in sucking his thumb.  He works really hard to get it into his mouth, but once it is there he is very content.  He doesn't try to suck his fingers or knuckles.  He specifically wants his thumb.
