Autism

My husband refuses to believe Autism is a real thing. Instead he blames me that our eldest is in special education and has autism says its my fault that he has problems. And I know he'll blame me too if our toddler ends up diagnosed which I suspect because he hasn't said any words besides mama and dada and he's almost 2. I feel like a failure as a mother. And he doesn't make it any better by blaming me.
