The comments about dad laughing and her reaction to it do bring up a good point. But I don't think he's laughing at her as in making fun of her. My baby girl does stuff that we find incredibly adorable and we get so overwhelmed with joy that sometimes it results in laughter. And sometimes for me, even tears of utter joy. I know I make an incredibly ugly face when I cry, even happy tears, and I every time I do it I really hope that I am not communicating something to her unintentionally. I can only hope she feels the overwhelming love that is overflowing out through laughter and happy tears. Fun video!
