As a female director level, I am happy for her and hope it works out. My ex is an ex because he did not support my career among many other control- related issues and extreme narcissism.
When I started doing well in my career, my DS was young and I had make lots of decisions to make sure I took care of him. It wasn't easy and I divorced his dad when he was 6. So my career had several changes as I tried to be there to see him grow up, but still maintain my career growth.
For me, growth meant continued learning but not necessarily getting promoted all the time. I had titles up to director and back down to manager and back up to director, not due to poor performance but my choice to be there for him.
I married again when DS was a teenager and it was great to have a husband who was supportive of my career, and who always offered to do some of the errands or pickups.
I don't regret my choice, DS grew up well adjusted, just graduated college in May, with no additional semesters, and got a job 6 weeks after graduation.
I think having a role model who was happy and successful in her work helped him make his career choice and give him a focus and goal.
So my point is that a working mom can have a successful career and happy kids as long as she remembers her kids come before work...AND if her husband is supportive.
