Ages and Stages

I've noticed a certain trend in learning during ages and stages of development.  Either it's genetic and that's why I see the trend, or it is a common event for a large number of children:)

Age 4-6  Learning happens naturally as a part of life.  They seem to soak things in and ask a lot of questions. For some kids, K-1st gr material will be very easy, as if they already know these things and don't really need to be formally taught.  Innocent and optimistic, the world is full of wonder to be explored.

Age 6-8  Suddenly, they seem aware of what the outside world thinks of them.  They seem hyper-sensitive to criticism and joking.  The workload gets harder and more academic, but the child doesn't quite have the study skills yet to adjust.  This new sensitivity coupled with the increasing challenge of academics creates a real rough patch in the 2nd/3rd-4th grade years.

Age 9 or 10  The "Real" Child emerges.  They come out of that volatile stage.  The parent begins to see a vision of where the child might be headed, his/her strong characteristics, interests, and natural talents. The child enters the "logic" stage, and has a deeper understanding of how things work.  He begins to question, and thinks of the world more critically, challenging ideas. 

That's all I have so far - I haven't seen anything past age 10 yet!  I'd love to hear your experience with your own children.
