My wife doesn't really have the earning power to justify putting our two toddlers in daycare. We have been talking about her taking in a few kids in an in home daycare. Anyone know of any good resources online that we could get some info?

The best way would be look into your local government as they will have some info on resources.

My MIL actually worked for the state certifying daycare facilities. There are many rules and regs that depend on the state, and the city you live in. Basically if you have some kids at your home that you are not taking care of full time, the rules are considerably less restrictive than if you have children in a home (or building or room) in which you do not live at. If it is the latter, the manual is about the size of a large phone book what you do need to comply.

It can be a great way to earn money if your wife likes kids and you have the set up to do so.

You may start from here: childcare.gov to find some base info and regulations, but also useful resources....
