The babysitter took my 18 month old to the post office. She created quite a stir when she began to speak-not only about the line, but about how people must be feeling when they waited in such a long line, what a waste of time it was, where did all the mail go, etc. When we look at old videos, it is a bit scary to see the verbal fluency. It was our reality but both kids were carrying on full conversations by a year old and thinking deep thoughts before two. They still are big talkers.
