Have you thought about opening up a daycare from your home? They do VERY well in my area and most providers charge $125 per week ($25 per day) for childcare and watch 4-5 children full time. They do have to pay their own taxes since they are a small business owner, and have to buy food to feed the children, but it would allow you to be home with yours, plus provide affordable daycare for someone else.
There is also transcription work and customer service work.
www.alpineaccess.com does customer service work from home and pays $10 or $11 per hour I believe and you're an employee so they deal with taking taxes, etc from your check.
I work at home as a transcriptionist for the past 5 years. So you can look into general transcription companies as well.
