Such an interesting conversation, I would like to add to it too
It is definitely doable and it was for us as a family with the help of hubby as a team effort and a nanny/childminder.
We had a combination of childminders and nursery after I went back to work with my first (childminder) and second (nursery and childminder). But as the last person said here it is not only in the early years that the kids need us, it is also and more afterwards when they start school etc.
So making an effort to work and progress a career is great if that is what you enjoy and if you love your work. I have always worked and went back after my maternity leaves after 6 and 7 months (doing progressive days, i.e. used up all my accumulated leave to work initially a couple of days a week and progressively increased to 4 which is what I kept it at for the past 7 years).
However although I enjoyed my work it wasn't exactly the kind of dream job so at the moment I have started my own business (photography) and also doing freelance work (in marketing) which is all new and something I am building.
I would love for it to work but I also would like to be in a solid position for afterwards once my kids have grown. So its an ongoing effort but with a plan!
I believe everything is doable as long as really work on it and put in the effort!
