No, I did not. Please read more carefully.
The sentence in question was:
“It’s unfortunate but true that with an increase in parental age comes an uptick in the likelihood of certain types of disabilities in children conceived during that timeframe, while also placing the associated realistic burdens, both resource-based and physical, on an older and physically-frailer parent: a parent who, at 45, has a child who requires certain types of care, is going to be lifting a 100+ pound adult as a 65-year-old, or perhaps dealing with early-onset Alzheimer’s in a child with Down Syndrome while dealing with their own aging issues.”
I said that the risk of “certain types of disabilities” (a broad category which includes, but is far from limited to, Down Syndrome) increases with parental age, and then mentioned two specific examples: an adult child who cannot walk, thus requiring extensive physical support from a caregiver, and early-onset Alzheimer’s in adult children with Down Syndrome*. I did
not say that Down Syndrome itself generally precluded walking, only that there are other disabilities which can.
A blog I often recommend is Passionate Perseverance, which is written by a Catholic mother of a severely disabled child. In it, she documents, honestly but with great faith, the challenges and blessings of having a child with severe disabilities. Her daughter was in her early 20s when she died a couple of years ago, having never walked, toileted, stood, etc independently. The author, Mary Lenaburg, doesn’t pull any punches about just how hard it was, even as a rather tall, strong woman, to lift, carry, and general care for her daughter; her husband helped as he could, of course, but he and her adult son had to work during the day, so most of the burden fell on her. At the same time, she leaves you in no doubt what a great blessing Courtney was to them and to the world. One of the many reasons I appreciate her point of view is that it is so realistic while also recognizing at all times Courtney’s (and, by extension, anyone’s) worth as a human being and child of God.
*By age 40, a majority of individuals with Down Syndrome have Alzheimer’s disease–see
