My 2 year old loves music but would only spend a few minutes with this one at first. He hasnt quite caught on to the tapping-to-play-the-song thing yet. Today we used the app for the first time since the update that added the "sing along" feature and Row Row Row Your Boat and he stayed with the app for 20 minutes plus! (thats a lifetime for a busy toddler!). He really enjoyed sining along with the voice. We hope that more songs are added in the future
