Hello, I do know a learning disabled and neurodivergent relative who is a parent. Their partner isn't learning disabled. This relative has always wanted a family and for most of their life they thought this wouldn't happen for them because of "the way they are" (not my words). They are a very caring and involved parent, very proud of their children and engaged with their interests, schooling and looking after them.
Obviously this is a different situation to yours but these are well loved children in a big wider family and they're well supported. Also, as others have mentioned, learning disabilities vary a lot so please don't take all of the responses here to heart, you could well be living a very full and independent life already.
What sort of daily support do you have at the moment?
I don't think you're going to get the best advice and support on mumsnet.
Do you go to any support groups local to you? I'm thinking of some of the organisations near me who I've worked with or have supported people I know. I'm in Wales so they might be different where you are but Mencap has local groups around the UK, Learning Disability Wales are great, Mind can help too.
Here is some Easy Read information about how parents with learning difficulties or learning disabilities can be better supported: Easy Read - Parents_web.pdf
There's more information on the whole National Children's Bureau website here: Resources for parents with learning disabilities and learning difficulties
There are some very worrying comments in some of the other posts. Learning Disabled people have the same Human Rights as everyone else in the UK, they have the right to marry and the right to start a family.
I think it's great that you've thought about it and know you need to find out more before you make the decision.
Caring for babies, toddlers, school children, and teenagers can be hard for all of us. Becoming a parent is a lifelong commitment to supporting that baby who will grow and become an adult.
There is support and advice out there.
