So much judgement in this thread.
I'm disabled and have chosen not to have children. People often assume this is because I am disabled, and congratulate me on my sensible decision. I did consider the practicalities around my disability, but it was part of the reason, not the only one, and I may well have had children in other circumstances, while still being disabled.
I know many disabled people who are excellent parents, whose children don't have caring responsibilities, this isn't about whether someone is disabled or not.
I also know disabled people whose children are a bit older, who want to get their kids to take some responsibilities and give them some chores, some tasks to help around the house, and worry their kids will get labelled young carers as a result.
Consider that if we are living in a society where school age children regularly take on caring responsibilities for their disabled parents, that might be because we have a social care system which is properly on its knees.
I live alone and have just had major surgery. The NHS gave me a couple of bits of plastic for the kitchen and bathroom to make things marginally easier, but at no point did anyone suggest I may qualify for social care. I ended up paying for it myself because I just wasn't coping / didn't feel safe.
People who look at this issue and suggest disabled people shouldn't have children could probably direct their energy into suggesting we have a social care system which supports those who need it.
