I've never prioritised alcohol or a night out with the girls over my kids
What do you mean by prioritising in this context?
Do you mean just doing something while not doing something else?
So I have often prioritised other things over my kids: having a shit, brushing my teeth, cleaning the sink, going to work, getting dressed, brushing my hair, reading a book, watching a TV programme, posting on Mumsnet, phoning my sister, answering the door. Etc. ad nauseum.
Which things are acceptable to prioritise over being in the same space as your children and which are not?
Think about what you are saying. Really think. Using the word priority there, is purely and simply designed to imply that by doing something other than looking after her children, a woman is not living up to acceptable standards of motherhood. Ask yourself whether you really believe that and if so, why. Be honest with yourself. And then maybe admit just to yourself (not to Mumsnet, that might be a bit of a stretch) that the only reason you used that word, was to be nasty to the OP. Then ask yourself why you feel the need to be nasty to other mothers.
I don't mean this just to be nasty to you. I think it's important that women recognise their internalised misogyny and try to fight it. It is not good for them psychologically and it sours their interaction with other women.
