Having been child free for most of my productive life (due to infertility which I accepted, no interventions. Happy with my lot) and then unexpectedly having a child as a 'geriatric' parent, I think I have experienced both sides. When child free, the world and it's dog thought it was within their rights to question my child free-status and assert that I could not be complete as a woman due to not giving birth. When I unexpectedly became pregnant, I was late in pregnancy when it was confirmed (I would not change it now), but I was perfectly happy with my life as a child free-adult and it was difficult for lots of reasons.
I adore my DC 20 years later, as did their father who died suddenly when they were aged 8. I have not been a perfect parent, but I have raised an amazing young person who has is now in uni, has worked alongside study since 16 and shows far more empathy and consideration towards others, particularly those with lesser life chances, than many adults in this world. They are thinking of joining the police, which I totally support because (full disclosure- I am a public sector worker and have been a nurse and then a child protection social worker for 20 years). Our society needs public sector workers, but more importantly young people from different backgrounds who break through the misogyny, corruption and stale, white male stronghold.
Attitudes towards child rearing and women have not changed much at all. When I had DC, after mat leave I was the full time worker because DH could work agency shifts as a highly qualified medical practitioner around my hours, and he was treated like a complete novelty. Years later, many of my colleagues work part time 'because the cost of child care' makes no sense to them, despite the impact on their pension and progression, they are all women. Society has not changed at all in this way, however most women with a professional career (not the few outliers in finance/corporate law who can afford a nanny, just the usual teachers/nurses/social workers) are now expected to hold down their jobs whilst remaining the main caregiver/responsible for sorting out child care and household.
I have lots if relatives and friends who remain child free by choice and who are amazing and remain a very important part of our life. I doubt very much that their decision has had any meaningful impact on the way parents are viewed. I suspect society's attitude towards parents is based on a growing sense of entitlement from certain parents, the increasing lack of empathy towards children and young people in general and the continuing breakdown within communities/extended support networks.
Women choosing not to have children is absolutely okay. Attitudes are nit changing because of it
