Our son is almost 7 months and was bored so we bought this toy based on reviews of top 10 toys for children his age and he LOVES it. Immediately he went right for it and plays with it for hours on end. He plays with all the different features, even opening the book which surprised me but they obviously know what they're doing. One thing I noticed is when the batteries get low instead of playing slower it will just stop or start repeating/skipping. This is scary at first because it sounds like it's broken; oh and watch out when cleaning because the pictures in the book are glued on paper which can get wet and tear, especially if you are wiping it off.
