I have sympathy for those who are children not by choice, I was that person until I was 34. It came with a lot of heartache.
Those who are children by choice? I envied them, I wanted to be happy with a career and holidays and my relationship and my dog and I WAS but I wanted children badly and it coloured everything.
Now I have children and I love them and being a parent. However parenting small children in a 2 person working household is a lot of juggling and trying to make things work and those pre school and early primary years I do think it's fair to expect a bit of leeway.
Same way that I think it's fair for those who are elderly or disabled or economically disadvantaged etc etc. I think everyone deserves some compassion and concessions for their circumstance.
Mother's and work, the stage where having small children impact your work life hugely is a few years, in the grand scheme of a 50 year career this is a blip. All this 'exoecting parental leave, why am I paying for your choices lalaalal' we pay for everyone's choices, society is made up of a lot of people in a lot of different life stages.
Best example I can give is during lockdown with my son at 2 yr old and working for the NHS while husband also a key worker but couldn't put my son in childcare due to his health condition was bloody hard. One fo the most exhausting things I've ever been through.
My single childless sister was stuck working in a new city, she kept her job, WFH and had lots of downtime. Did I envy her? No, she had isolation, lack of company, lack of meaningful in person support. She didn't have the loving cuddles I had with my 2 yr old, she didn't get to see her neices and nephews that she loves grow for almost a year. She also didn't have the working all night, parenting alone all day juggling act myself and my husband had. We both had a really horrendous time in lockdown for totally different reasons.
There's no reason not to have compassion for others whose lives and choices and life stages are different
