Quitting my job

Ashley
So, as the 6 month mark approaches I've been thinking every day of turning in my 2 weeks notice and leaving my job. I have no intentions of returning after baby is born, have been unhappy with my position for a while. And now that summer is here and my 5 year old daughter is about to graduate from Preschool (😢), I really want to spend these last few months with her before baby comes and before she starts Kindergarten.. 
I've told my fiancé this, and he seems nervous. I know it will be harder on one income, but I want to enjoy the remainder of my pregnancy instead of stressing over work and not spending time with my daughter... Any advice? Or any women out there who live in a one income household and made it work?
