Casting a Child's Account

This is something I would value for my two children's supervised account. They often need help and it's so much simpler talking them through steps when I can see what they are seeing using my android phone or TV. Please add this functionality soon.

This is surely a design bug. A adult account must surely be able to carry a supervised account. That's what "supervision" means.  Super+ vision.  There's a lot going on in scary baboon that needs guidance and parents are locked out. Surely meta can improve this.
