Chances of my child having autism?

Caitlynn • Mommy of a 6 year old girl and a 2 1/2 year old boy ❤

My boyfriends family has a history of autism. His older brother has some form of it, his uncle does, and his cousin. All three were the first born male from their mothers. They are all on my boyfriends maternal side. I'm not sure what exactly they've been diagnosed with but I'm just a little nervous. I'm having a boy and this will be the first boy. I have nothing against autism or anyone with it. I just want him to be healthy
