Ipod for babies?

Alan has an ipod touch. We have downloaded several baby apps for them here and there. They have just started to really take a liking to it. Before they had little interest in it and now they see it and go flocking to it. Levi has actually gone into Alan's pants pocket to get it out and play. Their favorite app as of right now is an animal app. A big red smilie face shows up and when they push it an animal comes on and makes it's noise. It is very cute and they have gotten pretty good at pressing the button. Hopefully some day they will start making the noises with the animal! Of course I hope that once it gets warmer we can go see some of these animals in real life instead of on a little screen.
