I'm not very keen on that article.
The idea of keeping a sense of independence, ambition, freedom while being a mum is interesting and important. But I agree that the article sets up a straw man argument.
E.g. "Mothers in the UK, generally, tend not to have conversations which stray beyond the confines of domesticity."
What????
"Mothers still talk about the exhaustion, guilt, anxiety and loneliness they suffer but do not have an explanation as to why this is so."
No, I think we can clearly see why we'd feel this. Also why do people keep telling me I must feel guilty? I don't! I do my best.
And I think she overdoes it in the "Characteristics of patriarchal motherhood". I mean, there's obviously pressure on mums to keep it all together, but "mothers must lavish excessive amounts of time, energy and money in the rearing of their children"?
"The mother has full responsibility but no power from which to mother" Many have a partner with equal responsibility (though often there less due to work) and have legal rights, the ability to access information, power to get divorced/earn own money. I don't get what she means by no power.
Imo, what would help mothers feel less constrained by motherhood is simply more breaks from full-on parenting (provided by partners, family, friends) in order to do their own thing.
