I had the privileged volunteering in that field and caring for disabled people is a good friend profession - I'm not a fan of romanticising it. A lot of parents might make positive experiences with their children, but when the reality hits that they will never care for themselves and the awkwardness of dealing with their behaviour once they reach puberty or adulthood - it's not pretty. It's not "a blessing", even if the mommyblog chooses to cope that way.

Will to live in mentally disabled people is iffy as well. I have a great aunt with Alzheimers that is quite intent on living when fifteen years ago, in full possession of her faculties, she would have chosen Euthanasia, had there been infrastructure for her to do so. The sane women wanted to die, the brain damaged one clearly wants to live. At least for people born with mental disabilities the person that might not have wanted to live like this never existed - they're neither sage on what lives are worth living nor completely incapable of having an opinion on their own fate.

But my entire point is actually that we do not have to try and untangle this because there's just no need to interfere in peoples family planning. We're not so fragile as society that we cannot leave the decision of what's right to every individual couple. It's just one of those cases were you make your own hard choices and muster the decency not to have a vocal opinion on other peoples choices. Posting on reddit about who should or shouldn't be aborted because you don't like seeing people drool on themselves in your favourite restaurant is just ... ugh.
