I understand their reasoning. Why not just “terminate” your first-born daughter as well?
The law won’t let them.
On that note every day I read about more and more medical hope for patients with dementia. If I were these parents I would have had both kids at these clinics for medical testing and what ever was coming out. I’d demand they try out anything/everything even if it was experimental. Something might work you never know. At least try. Abortion is not the answer.
They didn’t know the first born baby had the lethal disease until after the baby was born.
