I am in BC but it is the same answer - the guidelines are telling you what the youngest possible age grouping you can have is: Child 1 = 0mos, Child 2= 0mos, Child 3= 24mos, Child 4 =24mos. So you can have 3 kids over 2, but that doesn't mean you still get 2 under 2, it just means now you can only have 1 under 2.
