Ok so my daughter who is now 2 and is already as sarcastic as me loves these books. We have 3 of them, all different as why would I get 3 the same. Anyway if you want to be constantly asked by your kids "What's that?" everywhere you go then get these books. It can become very tedious but they are little young minds which are inquisitive and for one I like the fact that my daughter wants to know what things are around her. These books have helped in her development so I am pleased.
