When Denton gets tired he gets really silly and he giggles a lot. Just about every night when we put his pajamas on he will find something to giggle about. He use to giggle when we would zip up his pajamas, a few nights ago I told him "you better sleep in tomorrow" he thought that was a really funny joke!!! We love to hear him giggle it is one of our favorite things! We finally captured it on video so we can share it with everyone. (sorry the video is recorded sideways through some parts) We have so much fun with him, he is such a sweet little boy!
