There's so much speculation about child development, some as if children constantly need bundling into a kind of adult-bound lift. Press the button to the top floor: MATURITY. 

This is very understandable. You could say that children are, at the same time, physically immature versions of adults and that they are not. Only believing the former misses the point of what brain activity, at any point, is doing. This will, hopefully, be the best brain activity, with the brain in its best form for that activity, for the task of becoming an adult person. Piaget says something like this, as does Jensen.  A child's thinking is organised differently from an adult's.

Parents: resist seeing what your child is doing now as a deficient version of what they need to do in the future. 

Encouraging that kind of activity rather than goading a child to behave as if they are older is the best thing, I think. The momentum of aging is a strange old thing.
