What do stay at home mommies do to make extra money?

Danielle
I am and have been a stay at home mom for the last 2.5 years, I've often found some side jobs for cleaning for family, I've started a newborn photography business and help my sister in law with her wedding photography business. Are there any other logical and real ways to earn money to help out the family? What have you tried that works or doesn't work?
