Cute. Love the stack of books as stool. Careful, though, this is the kind of photo plan that will very likely change course. :-/ (imagine books sprawled, toddler not "cooperating") A great opportunity to go with it and just see what happens!
Whoever shot this needs to work on the positioning a bit, but Love the idea ... Shot an engagement pic like this with the ring inside the heart. Would be cute to hang on the wall next to a picture of any kids they have :)
