For those of you with the My First LeapPad or the regular LeapPad: which books are good/bad?

[MarinaTwinMom]

Once we decide which of these to buy for our twins, we'll need to get a few books to go along with them. So ... for those of you whose kids have a My First LeapPad or a regular LeapPad, which books did your kids particularly like or play with a lot? Which books did they dislike or not play with much?

Thanks in advance for your help! :)
