I have the free version on my phone and just bought the full version on the iPad. My 22 months old likes it. However, please please do something with the Home button! She keeps pressing it all the time. Maybe you could make it "toddler Proof", when it takes a long 3 seconds press to change screens?
Also, maybe add more musical instruments that a child can "play" on. And add more animals graphics and scenes.
Thank you
