My 18 month old loves Itsy Bitsy Spider. Almost every graphic on the screen does something. While he doesnt play with it more than a few min at a time, he doesnt play with anything that long! My older son also loved this as one of his first apps around 2 years old. Only wish there was some way to program a combo of buttons to close the app as I constantly get an "uh oh" and the phone given to me to restart the app since he likes to also push the home button (a problem for just about any app!)
