his thumb!
ds is 8 weeks old, and has a dummy. But the last week or so he has discovered his fist, and will sit there munching on it.
Well, he munches on it when he can actually get it into his mouth... he keeps missing and hitting himself in the face!
Right now he has a dummy in, and is also trying to force his fist in the side!
It's SOOOO the cutest thing I EVER saw!
