J.S.
You chose to be a SAHM for a reason. You have just a few short years to be with your youngest before she's off to school and then plenty of time to work during school hours. You already have an amazing, well paying job in a different way and the best way possible.
I worked when my kids were little and deeply regret it. I wasn't able to do it all and my kids and family suffered greatly.
Jobs may come and go but your family never will.
