I have worked FT since I went back after maternity leave when DD was 6 months old. She's now almost 10. I had a period where I was doing quite a lot of work travel, obviously not at the moment. I have worked myself into a specialist role that I love and been promoted several times. My thoughts:
I don't regret it one bit. Sometimes it's been hard and tiring, but I feel stronger and really fulfilled through my job, and I think I'm a better person at home because of it.
We had grandparent help, quite a lot in the early years. Couldn't have done it otherwise.
DD has always been fine with it, always knew both DH and I worked, never questioned it. Most families at school have two working parents.
I have a great flexible employer, I never missed a nativity, a bring your parents for lunch, sports day etc. It would be harder and I would probably feel guilty and like I was missing out if that wasn't the case.
I work in an industry that is generally very diverse. Women in senior roles and both male and female colleagues and clients frequently and openly arrange meetings to fit around childcare needs, or choosing a 4 day working week.
My work was only 10 mins from home which made it all easier.
I now wfh and will likely continue to 3 days a week. I love that because of compulsory wfh since March, I've been able to do what I never thought I would, like make DD on a rainy afternoon and get her settled with a blanket and a movie, or pick her up on the bike some days and cycle home together.
So I did it, and I love it, but all the above mean I've been very very lucky.
