I don’t know how old the subject’s child is, but there is a pretty good music game called Simply Piano, which can be connected with a piano or electronic keyboard. Good for practice.

If your child is young, you can listen to more stories to cultivate your child's imagination. I recommend Rabbit Talk. You can chat and listen to stories. The voice-on-demand playback will not hurt your children’s eyes. But there isn’t a lot of story.
