Back seat mums

Dawn • Baby girl to arrive April 21

To the mums who have backseat drivers in their lives how do you handle them? My mother In law is a hard core backseat Mum. Questions and fight everything I do and whenever I try and confront the situation I get told I’m being mean and a bully. How does everyone else handle it?

Edit I actually do mean backseat in life not actually driving. Contantly asking “are you sure? Should you be doing that? Why are you doing this instead of that?”
