You also cut off the baby's elbow.
I would have liked to see Dad in a little closer - it would have felt more intimate. He kinda looks weird floating over the two of them like that, with so much space between her back and his neck.
What kind of lighting setup did you use? It looks a little flat, and there are shadows in weird places. It looks like you had a light off to camera left, but really low, so the baby's head casts a long shadow on Mom's chin. It also seems like you had some fill light coming in from somewhere - on camera flash? There's some really strange light on the baby's shoulder and back that I don't understand though.
