I would caution you to check with your condo rules before starting. Some condos do not allow you to run a business from your home. Some condos set limits with how many children you can have (that differ from the Ontario laws, one lady on here can only have 3 children versus the 5 she would otherwise be allowed to have).

It would be wise to check and get approval in writing NOW before she gives up her job when her mat leaves ends.
