I've seen threads here where `OP describes the scenario where a partner moves in and is critical of the parenting skills of the parent , their partner.
My partner of a few years tried this a bit at the start. I tried to placate him and be the peacemaker and became a bit stricter with my teenage children . No bad thing really - they now always clean up after meals etc and keep their rooms decent which I didn't insist on prior to DP.
But he still would try to criticise my children for being lazy and suchlike. Saying I was too soft on them etc.
I woke up to this and stood up to him and told him not to ever criticise my children and things are better now.
So is this a common situation?
