The thumb!

Why is it that when it's your kid everything they do is so amazing?!!!! Sterling was talking himself to sleep 2 days ago then got really quiet. I went in to see if he had fallen asleep to find that he had discovered his thumb : ) !!! He was going nuts on it! He has no concept that it's actually attached to his hand so when he jerks it and pulls it out it makes him so frustrated! It's so funny to watch!!!
