There are a multitude of books and videos out there about getting your child into acting but most have no value in the long run. I have included links to some that I found helpful, but the bottom line is Agents want children who have natural talent not over-rehearsed mimics.
I have also listed below some of the more useful websites you should visit. They can provide you with well-rounded information so you can make a decision for your child based on knowledge. It takes a lot to be involved in this business and information is key to a successful career.
If you have any further questions please email me.
