Pinky, yes I have. Several people have indicated that SP's son is exceptional and that the reality is most people with DS are far more debilitated, especially in adulthood.
If you look at the actual data (available from the DSA or from DSE International) you will see that the learning disability distribution is a bell curve. Yes, there are a small minority at one end with severe disability and little independence. There is a small minority at the other end who function highly and have an IQ of up to 130. Most are in the middle. Slightly less able that the general population but actually there is significant crossover.
Please look at the myriad of peer reviewed academic papers from the last 30 years on DSEI's website showing how good educational outcomes for people with Downs can be achieved with the right teaching methods.
Blackcat, thank you for your wisdom. Now let me help you out. Tomorrow evening I will go out for dinner with 16 fellow mothers of children with Downs. Every single one of us works. I have been promoted twice since my child with Downs was born. None of us has a nanny. We all have multiple hospital and therapy appointments to keep and you know what? It really isn't that difficult to juggle. We don't live at the hospital.
Violence and aggression are NOT features of Downs. Some people with Downs may have dual diagnoses (including autism or ADHD) and some may exhibit problematic behaviour born out of frustration if they have not been given the tools to communicate effectively. The gap between receptive and expressive language in many people with Downs is huge and this can naturally lead to frustration, as can a feeling of powerless when they are not properly involved in the direction of their own lives or care. Happily, education techniques are light years ahead of where they were 30 years ago so the prospects for younger people with Downs are much better. Behaviour is communication Please understand the difference between a reaction to an environment by a scared and powerless and an inherent feature.
Where would I expect them to be? I am a member of 2 large regional groups for families of people with Downs as well as having links across the country through other networks. I think if this 'many' unable to walk or talk existed I might have come across a few. You are talking about one end of a spectrum and a SMALL number of people; your assertion is outdated to say the very least. We are normal people with normal families and children in normal schools. Are you aware of the Hampshire cohort study which showed how much better the educational outcomes for average children with DS is when they attend mainstream school.
I don't know where you amassed your experience but it really, really is not representative of the Downs community. Don't make our job of advocating for our children harder than it already is.
