Well I think I'm doing ok. I work 4 days a week, well paid, fairly 9-5pm (though i flex it when needs be). I am a well connected expert in a narrow but important field and I've leveraged that for all its worth to get this job (which was offered to me on my first maternity leave). I also completely changed career direction in my mid to late 20s in order to build this kind of career, so I could balance it with having a family. It's working out better than i could possibly have hoped. Not a lawyer, though i think our in house lawyers get a better work / life balance than those in legal firms.
There are choices in the shades of grey beyond high flying / full on and SAHM. i would say at the moment i am deliberately choosing to middle fly my career, so that I can be the kind of parent i want to be. I'm doing well in my job, I know, privately, I could be doing more. I'm not so that I can leave promptly each day, and have proper time off to focus on my children when I'm not here.
Maybe this means I won't climb as high as if I was full time full on. On the one hand, that's my choice, on the other hand, i'll never know. What i do know is I'm happy in my choices: for me my parenting is at its best and most joyous when I have space and time for them. If anything I'd like to brake a little more, have more time with my children.
I wouldn't want to be a SAHM though. hats off to those that do, I'd go bonkers, over thinking everything. I need work as an outlet for me.
You do need to reflect on what you really want. More time with your family (and for yourself)? Then reshape your career (including looking and thinking outside of the perhaps narrow path you are on. Maybe you'll fly less high. But then again maybe not. I think motherhood has focused me like nothing else. I have perspective on my job and I'm fearless at work now. Who knows where that might take me, especially when my kids are older.
Really want to kick on with your career? Get your husband to slow down and parent more, or if he doesn't want to, hire more help (live in nanny? housekeeper?). We've got a nanny that cooks for us and a twice a week cleaner. I outsource everything i can: I earn well, anytime i can buy back with money, I do. if I leave work late i get a taxi home to have an extra 15 mins with my children before bedtime.
I don't think you can have everything, but i do think you can have what's most important to you: you need to figure out what that is!
