I don't configure my child's accounts as minor. I don't tell it is a child. The work I have to do to comply with different weird stuff when some platform knows a user is a child is so much crap that I get a headache! And it often does not work properly (eg try to signup child account for PokemonGo on slow device, or try to allow network play for a child in Minecraft game - microslop family crap will hit you hard)
