There is the fact that it's nice. You can find people going through smiler struggles to you and get support and ideas. Example: My son is autistic and there are challenges raising a child like this (would not have him any there way!!). Locally I've gotten advice like I just need to smack his butt more, there's nothing wrong he is just quirky, I made him autistic with bread/vaccines, take away all his stuff until he behaves, that it'd be better to call him dumb/stupid instead of autistic, ect. None of these things work or are true
But online I'm part of a parent group where I can vent when I'm having a rough go, celebrate his accomplishments that neurotypical kids have long since past, and seek advice when I think I am doing something wrong or I am totally lost. I can't easily find parents like that around here because not many will want to speak up and say their kid is autistic too. So I can feel very alone around here very fast when it comes to situations that are not typical fo a boy his age.
So yeah.... sometimes it means we can have time to talk with people like ourselves that we can't easily find on our own.
ALSO... there is the added bonus of taking our time to say what we want and not rush through it and come back to it later when we are not as upset.
