I made a deliberate decision NOT to stay in academia.  I was lucky to have several great female mentors, but they had all clearly sacrificed in their personal lives to get tenure.  So, I am "in the field" - I love the work that I do, but sometimes I miss the intellectual challenge of university life, so I can relate to that aspect of your story at a very gut level.

We also had our own "tipping point" - we moved states when my DD was 5, both changing homes and jobs, and helping her in a new school.  We knew we couldn't do it with both of us working full-time, so I embraced the option of staying home, and then we had #2, and I had the delicious luxury of being home with him for 15 months.

Eventually, I was ready to work again, and have been fortunate to find a career that is not in academia.  Sometimes, at conferences, I feel like I made a lesser choice.  But mostly, when I can relax at home and not worry about the "hoops" of academic life, I'm happy with my choices.

Sorry to go on and on with my story, instead of offering you support on yours, but it just felt like a BTDT moment.  Things evolve, opportunities arise, and maybe you'll find a new career path when your babies are a little older, and it'll fit your lifestyle just perfectly!
