Care of self is one area that without thought our children practice everyday. Putting on clothes, brushing teeth, washing hands. For Otis preparing snack is also a part of everyday practice. Pouring, cutting, tonging.
It's a nice reminder that in the home not all activities need to be presented on a tray, on the shelf. Why not make practical life activities as practical as possible.
So many people say they do a lot of Montessori without thought, not necessarily subscribing to Montessori it just seems like a good way to do things. Yes, Montessori or not, a child preparing snack makes perfect sense.
