Autism Spectrum

I know that it is too early for a formal diagnosis, but are there any other mommas here that feel your July '17 little one is showing early signs of being on the autism spectrum? Or does anyone here have other children on the spectrum? I'm feeling pretty alone with my suspicions about my son and riddled with anxiety so I'd like to hear about your experiences, if you're willing to share.

UPDATE 10/2019: my son was diagnosed with autism. Trust your instincts mamma bears.
