I think parental consent is also extremely tricky. In my field of work, I have seen multiple parents of young children with chronic disabilities who have coerced or forced them to undergo treatments they did not want to undergo. I worry that this could be similar when it comes to MAID. I worry that parents who are scared of their children's disabilities and don't understand them would be able to do the same thing with regard to MAID.
I also know that parents have a lot of influence in how children feel within themselves too.
