Most states have an early intervention program, sometimes called First Steps. It is for children under three, it's free. After three, the public school system takes over. If you can't find it, call your local school system's special education department, and they should be able to tell you. They will come out to your house and evaluate your child in the areas of Physical Therapy, Language Development, Occupational Therapy, and Developmental Delays, usually in one day. Any therapies that your little girl might qualify for would be provided for in your house on a sliding scale, usually around 5-10 dollars per session. I hesistated to call them on my second son, but when I finally did, I found out that he wasn't hearing anything. I wasted lots of time that could have been used with thearpies to help him because I thought he'd "catch up". The best outcome would be, "She's fine," and then you can sleep well at night. Even if she qualifies for Physical Therapy, a few months of therapy will mean a world of difference. It's way better to know.
