Stressed with so many evaluations!

Am
So since the early age of nine months my son was exhibiting many strange behaviors such as banging head against things when excited and hitting himself. At his 1 year physical the doctor brushed it off because my son was able to count to 50 and recognize all letters of the alphabet both uppercase and lowercase. He had a huge amount of words and I insisted because I knew something wasn't right. Now at the age of two he has developed repetitive behaviors such as flapping hands, hitting his ears and lining up his toys. I called an early intervention center myself but I am rushed because he will be 3 real soon! Has anyone else gone through this? How was it and what condition does your little one have?
