My toddler enjoys this and has picked up a few words from it. It has animals, shapes, numbers, and a few other simple concepts. He enjoys "reading" it repeatedly. There are things to touch and feel, flaps to lift, and doors to slide. I'm not a huge Dora fan, personally, but I can't deny her appeal to my kids.
This is a great toddler book - my 4 year old regressed to it tonight but actually finished all the puzzles which she didn't do as a 3 year old. A fun set of pages where Dora has adventures in counting, letters, colours and more. Also a mini Dora story. There are flaps, unfolding hits, holes to peep through and more to make it a real adventure for kids who love Dora.
