Fun shot. You've caught the bubbles well which is not always easy. The smile and position of the hands on the baby look great. Technically speaking there is a bit of blur or soft focus in some areas toward the front which would have been better if they were as sharp as the adult's arm. Maybe to avoid chopping off the kid's shoe might help more too.
Wow, shoot this from the sides so you can't really see the adult holding him or the busy background and this would be the bomb! I vote for a reshoot...

Tucked this one right into my Fav's! Well done. Can't predict the finish - it's not a typical DPC formula shot, but to any parent of little tikes, it's priceless.
