There's no ideal work scenario for mothers.
Full time - barely see your children, spend weekends doing chores, too much stress, people think you have abandoned your children
Part time - out of the loop at work, disproportionately low pay compared to workload, people think you have an easy life as you're not working every day, pension situation
Give up work - can be impossible to get back into work later when DCs are older, financial dependence on partner and vulnerability, pension catastrophe, people think you are lazy / wet blanket / taking the piss.
We really can't win can we?
I worked full time as a primary teacher before having DC1. Returned part time which was manageable, very long days eg leaving house at 7am to get to nursery and back home at 6pm,working in the evenings, but I had long holidays. Dc2 was born and I remained part time after mat leave. Getting 2 kids out of the house was much harder and DC2 was often in hospital due to health condition. No family nearby but we coped. DH frequently worked internationally but also from home quite regularly.
Tipping point for me was becoming ill myself with a horrible chronic illness. I physically cannot teach now,even part time. So I find myself being a Sahm which isn't what I wanted. There are advantages of course, I can go to school events, pick the children up myself which they like, we have a much slower pace of life now. I do want to get back to work in the future though, health permitting.
