It's not impossible, but our quality of life is better for me not working. DH works long hours. There's no family support. When your child is autistic (even at the end where they can regularly attend mainstream school with little intervention) there aren't the mutual favours with friends to get you through things like INSET days. My job gave as I was too stretched and wrap around care was more than DS could sustainably cope with after yR.
He's a teenager now. I'm fortunate that he doesn't need 24/7 supervision, but the amount of time I can leave him for is limited by the fact that he won't register hunger/ thirst, and he won't prepare food for himself. He has a lot of fear about heat, and sharp items. He's also dyspraxic with poor organisation and hand strength.
He copes in school, but that's with a lot of down time, quietly at home. Things like doing the school run saves the additional load of catching buses at peak times. Without that level of support and down time, the wheels could fall off quite easily. (This evening he reached his limit at an event that he opted to go to and we had to leave when he got peopled out and started headbutting a building as a stress response)
I could hypothetically work from home, but that's not viable within my original sector and the thought of living in my workplace is abhorrent. It was awful when DH's company comandeered our home in the Covid years. I suspect that I may have ADHD and the thought of constantly battling myself and clashing work/ domestic commitments in my home space and having no physical boundaries is something that I would have to be totally desperate to endure. I already feel like I'm permanently trying to coax my own ignition into action.
We've also had a couple of school years where DS2 has had health issues affecting his attendance to the extent that would really test the patience of employers (even if sharing the load with DH where possible)
