I'm sorry, but I'll have to answer in English. I was doing Duolingo until you all came in.
What we imagine and what really happens when a child is dying are two different things. I think it would be so clear to anyone. By the time a child or youth actually decided to embark on this pathway, their disease would be so advanced that there would be no question. In fact, I've seen very much the opposite happen, where I've had a few patients who could have opted for MAID—they were past their 18th birthday—and have not. I have actually had one 19-year-old die by suicide when his disease became too advanced, but not through the channels we're talking about.
The assessment would not be difficult, and I think parents by and large eventually come to see what is happening to their child and become supportive, even if it takes some time.
In the case of younger children, the parents can see what's happening and wish they could exert some decisional capacity over the situation as they would for many other health decisions they make on the part of their child, but I don't think the evaluation would be difficult.
