I care for children 6 months to age 5.
I really like the Montessori approach and base my routine and plans according to many of it's ideals/methods. One of the highlights of this approach is the role younger and older kids play within the context of group care.
The younger ones learn from the older ones and the older ones learn from the younger ones. I like the way it works over all and couldn't imagine limiting myself to just one age. I like the age span of infant to pre-kindy.
No school age though....that just adds an element to the mix that I am not fond of.
