Dixie,
As a Mother, you do what makes sense for your family and you make it work. You're a Mother and you're doing that. That's a good thing.
In our case, I make a little over 3 times what DH makes. No way I can quit. Our goal, though, is for DH to be able to stay home soon. He took FMLA when we adopted. Unfortunately, I had to go to work. My boss, though, got it. He let me work remotely a lot. But 50+ hours, oh yeah, that's expected. Took a new job this fall. My new boss, an adoptive Mom who makes 3 times what her DH makes, she gets it. I also have an elderly Mother (lost Dad a little over a year ago) and she gives me space to care for her too. I am totally lucky. But, dang, I'd like to be home with my baby.
I'm only writing this to say that we all have to decide what's best for our families. But instead of letting your situation decide for you, you're taking the bull by the horns. Good for you.
We have a good friend who decided to work from home. She became a medical transcriptionist. Makes lots of money working from home working the hours that work for her family. Several other friends have gone that route recently. Might be something you want to look into. You have lots of options and you know your priorities. You're a Mother.
