When she was in school the teacher let her stand since she was between sitting and standing and that habit contributed to falling out of the seat or flipping it. She was also the size of a three year old so the tables were too high for her.
When they are younger it is easier to O.T. weak areas.
Interesting because I notice a big difference between my DD8 (and only 26th percentile for height/weight) sitting at the kitchen table vs the table in her room with a smallish chair and 3 height adjustments. She too has a tendancy to sit on the edge of a chair, swing her legs, fidget, things like this. She is fairly agile though so she tends to just balance there and not often actually fall...
Last year's teacher said they do that until about 4th grade, when it suddenly all seems to catch up that the mind can control the body, lol!
