my oldest has ASd but his two younger siblings do not have it

2 kids same father youngest is ASD and my older daughter is being tested for ADHD, ocd anxiety and has other problems we are just discovering sometimes i wonder if she is mildly on the spectrum too. genetics of depression anxiety and addiction sometimes i wonder if I was undiagnsed as a child with mild ASD and severe ADHD. being 35 a little late in the game. feel my kids we doomed from the start with their unique genes

My 16 year does and my 8 year old does not

I have 3 children, oldest is 17 and is not autistic 3rd and youngest son is 10 and also not autistic only my middle child, my 12 year old daughter is HFA

My first born son has Aspergers & my daughter is not.
