You can't have anymore that FIVE kids (not including your own) at the SAME time. Not even if they are b/a school kids that are there for just a little while.

BTW....once the child is OLDER than 10 they don't count in your numbers.

So, NO, you can not have 5 kids there who are toddlers, infants, whatever AND have b/a schoolers. Not at the same time!
