Thumb Sucker?

Last night I was cuddling with Gavin while we were watching tv. I looked down and he was sucking his thumb! I sucked my thumb as a child and didn't stop until I was in First grade. A girl in my class made fun of me and I was mortified! I hoped and prayed that my kids wouldn't suck their thumbs. That is the main reason I push the pacifiers on them. Eventually you can take that away! Even though he looked cute as can be, I am hoping this won't be a habit!!
