Is caregiving innate and adaptive?

You will see little four and five year olds taking care of the children at their school or day care. They just do it-no one tells them to do it. Their mothers and fathers will say that they are like a "mother hen" with children at church, younger siblings....I think it is innate because of this, because children in the same family are not the same way-only one of the siblings. How can they learn that at four and five and feel the need to mother and take care of them?

Maybe they are modeling what they see their grandmothers, mothers, aunts do? If not, it is innate. I believe teachers are born that way also. You are either a really good teacher, know what to do, and there are some that could spend fifteen years in college and not know what to do instinctively.
