I understand...most of us did as new moms . It was hard for me to decide between my career and being happy in it OR my baby and being (completely) happy as a mom. I tried balancing for a bit over a year - but felt miserable and guilty most days.
Once I decided Not to go back to work at any firm, I LOVED the first month. Then I got scared, as my ( my husband had no savings at the time ) savings got smaller & smaller. So we made MAJOR adjustments. Most people would not be willing to do that, and I understand. It's a HUGE sacrifice at first. I literally had no money to go anywhere or do anything for almost two years! Then it slowly got better and better!
BUT: you are only 4 yrs from financial freedom, so that's a goal worth working toward! My hat off to the pair of you! If I were THAT close.... It would've been a different story.
I'll say that neither of my 2 children were planned - so that played a BIG part in the trajectory of our lives. TWO BIG surprises
Having your 4 day week after the baby is born will made a big difference , you will love it
I actually worked as an architect (with my degree, but not 'registered'). Then went on my own processing permits For other architect's/engineer's projects. I'm still project manager for a few projects, while wearing 'multiple hats' on other projects. The business has grown into other areas. I'm very greatful and blessed for this opportunity. I use my extra time for my family. I love my kids more than life itself! Wouldn't want it any other way
