Check out my website on how to earn extra cash online. It's makemoneyonline.tonoftips.net None of it is any real jobs, but I make enough for groceries each week.
For real at home jobs leads, check out the forum at workplacelikehome.com They have lots of legitimate leads for at home work.
Depending on the ages of your children it may be hard to work an actual job at home. A lot of places require you to work with no distractions and things to be very quiet. So you may still have to find someone else to watch them or try to work at night while they are sleeping.
The different things that I list on my blog are all things that I can do whenever I have time, and I can stop if my children need something from me.
