My son has had this toy since he was 6 months old (He is 17 months now). We recently had to remove the legs from it, as he learned at 11 months to climb on top of it and then onto whatever was nearby, so beware if you have a climber!
Otherwise he was very entertained by the many sights and sounds on this toy. I really liked the fact that you can remove the legs. When he was a baby we left the legs off so he could play on the floor with it, and then when he was cruising and walking we could put the legs back on to keep him entertained. There's music and words and things to spin and flip open - so much to keep little hands and ears busy. A good toy for a baby that will last into toddlerhood.
