For a child of that age, would not a digital camera make more sense?
I'd rather go about this as a learning experience for her. I've let her use the DSLR (with AMAZINGLY CLOSE supervision), but this will be her first real introduction to any film process. She was too young the last time I had the cameras out.
No idea what's going to happen next, but I'm hoping it involves being wrist deep in chemicals come the weekend.
