Its up to the agency to dicide whethet or not you can have the 6st child. They have control on whether the child is young or school age. It is my understanding that a lot of agencies are going to use the 6 child ONLY for school aged (6yr +). They can't find many providers who will take children this age because the fee they pay the provider is a "sick joke".
Its getting very hard to find insurance. Sorry not sure who will cover the 6st child.
It is a good policy to keep an attendance record.
There is a website for parents that has a summary of the new laws and other information about home daycares in Ontario. www.ontariohdc.weebly.com
