I was a single mom of two working a full-time job and often a part-time as well. my son, who was naturally active had a hard time sitting still and i thought i was doing well by "training" him to sit for long periods of time.
all i know is that i don't miss the constant rushing to meetings or conventions. we were always a few minutes late and because of that, we were punished by being paraded up the aisle to sit in the front row over and over again.
