Austitic toddler

I think my 22 month old is austitic. He has a lot of the symptoms. He doesn’t talk much, stares into space all the time, sometimes doesn’t answer his name, he socially awkward(?) doesn’t really play with other children his age. He won’t be able to be diagnosed until his 2nd birthday. Anyone else’s toddler experiencing any of this? Please let me know. I’m worried.
