California’s Early Start Program
This program is often times one that your doctor may refer you to if there is a hint of some developmental lag in an area. The program is government funded and is run with great care. Developmental assessments are conducted, if you are eligible, physical or occupational therapists may be assigned and programs designed around your child are created.

I had a great experience with them when we were referred to them at one point, and I have several friends who similarly have used their services. Even if there is nothing severe in play, they are an excellent resource to help you make sure. And, more importantly, if something is going on they have the resources and knowledge to help you figure out the next steps.
