I don't have a kid but it so happened that my Mom forcibly tries to offer her services (food, advice, governance) so I know what you mean.
I don't want the governance so I don't need the favours. And what's the solution then?
- cut the communication, run to the edge of the world - but Mom will still call/visit you and do all the humiliation;
- force Mom to stop offering her services.
Which is ethical? Remember, reasoning won't work.
