Minecraft issues, won't let my nephew eat, or dig, or build, or kill?

It only does this on his account so I messed with the parental controls but that didn't help. It keeps saying 'you can no longer eat, you can no longer sleep,…' it won't let him build or mine.

If it's on xbox than turn on trust players if not than i don't know.

That game is horrible how can one like that game
