I've been on the list for a while but I recently signed ds up for it. I wasn't sure if I could do this at first but I looked into it and it was fine. When I said to ds dad he said it was wrong as ds had no choice in it. He was pretty annoyed. Ds is 2.5. I'm also sure my mum put me on the list when I was little, I vaguely remember having a card.
Obviously ds didn't make this choice but if, god forbid, anything was to happen to my ds I would rather another child could benefit and hopefully get out of the horrendous situation they are facing.
I know this is a bit morbid but I'm a student nurse so it's something that I've had to think about iykwim.
