Good Afternoon Samantha,To find out if Michigan is a state that allows you to do childcare without a license, you would need to call your local social services. What some states allow is one family, no matter how many children are in that family if you're doing care without a license.
For licensing information from state-to-state, go to Licensing a Daycare".
For specific licensing information in Michigan, visit their Department of Human Services page at www.Michigan.gov.
If I can help you further, please ask.
