Here is a small sample of great resources that are available to parents of child actors. You do not need to pay a dime, subscribe to anything, or support any entity. These resources are available for free through government resources, actor union resources, etc. Be diligent and use the free resources available to the public. If you need any specific resources for your area, feel free to email me at alan.baltes@gmail.com
