I don't know if they still make the software, but the Learning Company's Living Books software saved my sanity. Our kiddo could select to have the book read to him, and there were hidden Easter Eggs on most of the pages, encouraging him to touch all the hot spots and explore. The software also usually had either Spanish or Japanese versions as well, so when he got bored with English, he'd choose a different language.

When he was around 3, he completely memorized Harry and the Haunted House - complete with sound effects (... he opened the door ... reeeeeee....) and used to recite it to use over and over on long road trips.

If they're still around, I'd highly recommend them.
