peek-a-boo barn.

Logan's favorite game to play on the iPhone, hands down, is peek-a-boo barn.  He loves the animal noises and how the barn door opens to reveal what animal is inside.  He has a thing for dogs, so he goes nuts when the dog starts barking.  If you haven't tried out this game you can get a free trial from the app store.  I highly recommend it for toddlers, it will provide a good 15 minutes of fun & learning :)
