iPhone Baby

I have had the Wordpress App on my iPhone forever now and have never attempted to create a post from it, never had come upon a reason I couldn't wait until I got to my laptop. Well partially out of boredom and curiosity I found an excuse to create a post.
I've posted about my baby girl playing with my phone, and as her geeky father, trying to find new ways to entertain her. I've even posted reviews on some of the apps I've had the most success with. Well as proof of concept, I snapped this picture of Abby playing Peekaboo Barn on my wife's iPhone while stopping at a red light. I just find it entertaining how a 1 year old can be more aware of how to use a technical device then many adults (example: my parents).
Although I'm still up in the air on how much technology is too much technology when it comes to young children, I couldn't help but share this snap shot of my bug. Father's pride I guess.

iPhones and infants

I've realized that there is a growing demand for information for apps for what I'm calling iPhone Babies. I'm in the process of testing other apps with my baby girl (but Peekaboo Barn is still the take all home run).  What I'm looking for are suggestions for apps.  What does your baby enjoy, what gets their attention?  Paid or free, doesn't matter, I'm curious to see what other magic apps are out there for us tech savvy parents.  Feel free to comment below on what apps you feel fall under the category of "Must Have".
