Recently，I want to develop a App for my kid, please give me some advice.
Content：
1. My child was born in 2007，I find some phones with her every month since she was born, then make a Dynamic album.
2. Show our family videotapes and phones.
3. Write a little words that I want to speak to her.
I hope this App like 《Life on the earth》and 《Winter Forest》, this is my little dream.
(《Life on the earth》: on the iBooks .
《Winter Forest –Chapter II》: good app for kids. )
