When I first got this for my son (~1 yr), he wasn't super interested in it. He loves lift a flap books, but he would quickly skim through it and toss it aside.However, now at 17 months he can identify all his body parts and loves to look through and do the same with the babies in the book. When we get to the belly button page, he basically falls over trying to get a good look at his own belly button.While this isn't my favorite book, he seems to enjoy it very much so I would recommend it for children ~1 year old.
