While I appreciate your ambition, I can't see how it would be good to have someone that young learning on a 1D. The sheer weight of the thing is going to make it really hard for her to learn good form. I would get the lightest DSLR you can find, and focus on teaching her good form and composition. She'll have more fun in the long run I think.
It is kind cute seeing her holding it though.
Not everyone wants to spend money on another camera just for their kid to practice with.
