Summer of Transition...

If all goes accordingly to plan (and it never does), by the end of the summer, the Tonka should be able to swim with some degree of confidence, know how to ride a bike (with training wheels, but with confidence), have some proficiency in reading and writing.

That's a lot of learning in a short period of time and it makes you really think about the rate of acquisition of knowledge at a young age of life skills, particularly vis a vis the rate of acquisition of skills/knowledge at our later stages.
