Why not just find something to do making money from home? I've worked at home since being pregnant with my first child and I make almost what my husband makes working outside of the home full time. My work at home is done with part time hours, I fit it in when I can - like during naps, before kids are up and after they go to bed at night. Just depends on when I can fit it in.
I would highly suggest that you get the book by Liz Folger called The Stay at Home Moms Guide to Making Money from Home. Your library probably has it. That was a great resource for me when I decided to work at home so I could be with my baby. It will give you ideas on how to take your current skills and find a way to make money at home...and how to avoid all the work at home scams out there.
Going to work is going to disrupt your family. Taking kids in to babysit is going to burn you out on kids and taken a lot of attention from your own kids and possibly make them jealous. Take your skills and put them to use working from home to make money.
