Child casting from parent profile

Many of us parents have been suggesting (begging) for an option to be able to cast what our children are playing on their profile from our parent account. Please Meta, hear us and answer our requests! 
If you make it like a secure link with a code for casting it should be a safe way to do this. 

Sincerely, all parents who are tired of having to throw the headset on each time they need help or we want to check what they’re doing 😝
