Fully prepared to be told I am but here goes..
For context, my brother has autism and it's been very hard with him. I often feel protective because he has had such a hard life with bullying amongst other things.
So my Sil was over today visiting as I have an 12 weeks old DS. There was a loud noise and DS startled and started crying (for about 10 seconds) so I comforted him and he was fine. I then started telling Sil that he's just started to become overwhelmed by things and loud noises, lots of people ect can sometimes upset him if hes tired. She then says 'Oh god, hopefully he's not autistic' I couldn't really believe it and came back with something like 'wow, what a thing to say' and unintentionally gave a horrified look.
She is a very blunt person so I usually look past things she says as it's easier but because of my brother I couldn't quite brush this one off. I do realise this probably makes me more sensitive in this situation but I was shocked she said it.
Fwiw I'm obviously not worried about him having autism and it's probably too early to tell anyway.
So aibu in being shocked she said that to me?
