My DS is three and has been diagnosed with autism, he received the diagnosis just before his third birthday because I noticed signs very early on and pushed for early intervention.
Me and DH have long suspected that he is on the spectrum too. DS being assessed and subsequently diagnosed confirmed that to us, alongside the fact that his older son from a previous relationship (8) is currently on the diagnosis pathway for ASD himself as he is very clearly on the spectrum too.
So that's (at least) three members of the family that have autism.
You wouldn't know that though because my DS is the only one that people think is disabled.
DH's ex has never told DSS why he's going to these appointments or needed speech therapy, he's oblivious to the fact he's autistic.
He (and my other DSS) know about my DS having autism though and as such he's looked at as different / disabled and they treat him like a pariah.
If DS is having a meltdown when my step children are round DH will explain to his two sons that DS is struggling with sensory overload / transitioning because of his autism.
When DSS has a meltdown or struggles with transitioning he's just 'upset'
The fact his ASD is being kept from DSS is detrimental anyway in my opinion, shouldn't he know and be able to understand why he struggles with certain things.
FIL came round this morning and we were chatting, he was telling me about his previous nextdoor neighbour who's son had ASD and a learning disability, and how hard it was for the parents who had to call the emergency services multiple times when the young man went into meltdown and smashed up the house.
He said he hopes for our sake (me, DH and DS) that DS doesn't struggle so badly when he gets older.
Meanwhile his son (DH) is stood there nodding along, knowing he's on the spectrum and knowing DSS is too, yet does nothing to point out that actually that may not happen because he doesn't have outbursts like that.
AIBU to be pissed off that my DS' autism is public knowledge yet the others autism is a secret?
My son is not the odd one out
