Tate's Trick

Tate started doing the cutest thing a couple of weeks ago. He doesn't sleep in his crib at night, but he likes to lay in it and play with his crib soother toy. He learned how to push the button on it to turn it off and on. He cracks himself up when he turns it on and gets sad when he turns it off. At first we thought that something was wrong with the toy, but we went in his room and saw him pushing the button over and over again. Is he smart, or is it just me?? :)
