Please tell us where you live, which province, because the laws vary. In Ontario for instance I'm positive that we can only have 5 children in care plus our own children. There is no matter how many adults are working, 5 is the limit. Depending on your province look into the laws and rules of the Daycare Nurseries Act and I'm sure registered or unregistered will make a difference, but in Ontario, 5 is IT, registered, unregistered, adults in #, whatever.
