Hi:
In California we have something called Regional centers. They are state run clinics that 'test' infants through 3years in the areas of speech and Occupational Therapy. If a child is found to be weak in one or two areas, they qualify for therapy free regardless of income. My son qualified for two hours of speech and two hours of OT a week.
At three the children are sent to the school district to continue therapy. The school district and the regional center coordinates the transition together with your involvement.
Please go to your school district and find out how to get to a regional center. If you have your child evaluated you will be better off either way. The sooner a child receives therapy the better the prognosis. My son started at 2 years 4 months. I wished I had be more assertive earlier. Where would we be now?
Your pediatrician should also be able to direct you to these regional centers. However, my peditrician kept on saying my child was fine and I so wanted to believe him that I did not do anything earlier. (My son attends a regular school and is above grade level in reading and math. But he still needs both therapies. He can't ride a bike, feels very insecure about using a swing, and is years behind in sports.)
If you live close to an university, they may have speech and OT programs where they train future therapists. They need kids to work with and I have also found these programs to be high quality.
Good luck!
