M.S.
Btw, I also have 4 boys + 1 girl. :-) First, I would run the numbers and see how much you are actually taking home. Then, I would find an opportunity that you could do from home and replace your actual take home pay. You will be raising your own kids and making money too. Yes, you will need to take some time for yourself just like all moms. :-)
If you are interested in working from home, make sure you investigate the opportunities first. There are lots of options out there. I have investigated a lot of work at home opportunities. Some are legitimate and others are not. Find something that lines up w/your interests and goals as a SAHM. Personally, I never liked the party type businesses b/c: How am I working from home if I have to hire a sitter just to try to make some money? So, just be sure of what you are looking for.
Best wishes in determining what is best for your family.
