When your child makes eye contact with you then smiles at you, it is such an amazing feeling! Oh I was made for this.
We are so blessed to have such a happy baby. Even before he smiled, he was generally content and bright eyed. His face did a few times form an expression much like a smile. My guess is that the smiling muscles were already in place but the feeling of emotions such as joy had not yet set in. Now they have, undoubtably. Man, we love this kid.
