Wow, that brush is so broad! Where did you ever find it? It can be this, but it’s on the less likely end of the spectrum, and becoming moreso all the time with medical advances. Depends on the type of DS you have, for one.
It really depends on the child. My baby cousin (who’s 20, eep!) is a reasonably high functioning DS person. She speaks understandably, she reads and writes at about a fifth or sixth grade level. I keep up with her on Facebook, since she lives pretty far from me now. I love her to pieces, she cracks me up. But she’s a multi faceted person, not someone who is just DS and nothing else.
She’s had two operations, one to make her tounge smaller so her speech could be more understandable, one to correct a cardiac defect. She has her own apartment, which she owns - only because her father died last year, and her mother bought it outright with the insurance he had for my cousin. She was renting previously,a nd recieved assistance to do so. It’s better for her to own since she makes enough at her job and with disability to pay for things, and there won’t be any changes then and she won’t have to move. She doesn’t cope with routine changes really well at all.
There’s a state program which provides her with someone to check on her by phone or in person every day. She has a guardian who looks after her money, and helps her pay bills. (There’s a program she’s in but I don’t know much more about it, sorry.) She can cook for herself, and does. She keeps her apartment cleaner than I keep my house (because it’s hers, and she wants her dad to be proud of her - the thought of which makes me a bit teary.) She has a factory job, and makes her own money. Sure, it’s minimum wage, but its a real job, not just a make-work type one. She is taking classes to learn to bake, and is doing reasonably well. She’s hoping to be work in a bakery or a grocery store deli.
She was not your sterotypically sweet happy child, though. She could and did throw tantrums, hit and kick. This mostly stopped after she became understandably verbal after her operation. She can be manipulative and sneaky, if she wants. She does this now that she’s older, rather than tantrum. She can also be a ray of sunshine. Her sense of humor runs to sarcasm, and it cracks me right up.
She has a boyfriend, also with DS. She attended mainstream schools, had neurotypical friends and is active in Special Olymics as a volunteer now, although she played sports when she was younger.
She’s permanently about 13 in most respects. All her life she’s been taught to compensate and to be independent. Her mom is close to her, but not to the point where she’s involved in every aspect of her life anymore. And that’s ok. Her mom has always wanted to get her to a point where she can have a real life of her own, and that her mom can have a life of her own as well - it seems to be working.
Even when her dad died last year (her parents are divorced) she did ok. Not great, but ok. She was able to process it and accept it, although obviously she’s devestated, as were we all. My uncle was a pretty awesome guy. She didn’t go off the rails or stop going to work or anything. She needed about a week off and another month or two of reassuance from us all that she was ok and so were we, and she’s been fine afterwards. So pretty ‘normal’, for want of a better word.
She’s been educated about sex and where babies come from, and she has an IUD. I suspect she is intimate with her boyfriend. This can be an issue with DS people, is my understanding - having sex without understanding the consequences.
OP, I would be really sure you can cope with it alone - really, really sure. My cousin, and her parents have had to really push to get her where she is now - and she does have the mildest form of the disorder. If they had been less ‘pushy’ about getting her the education and training and support she needed the outcome for her - a mostly independent, pretty normal life - would have been vastly different.
Just be really sure, because people on a message board aren’t going to talk you into or out of anything.
