As for myself, I was just trying to sit straight in the chair.

Half the day would be spent trying to sit still at a desk.

She sat in the next to the last row and tried to sit still.

The first day of class I would try to sit in the front.

I tried to sit but couldn't raise my head more than a couple inches.

So just try to sit still and be good like Gary here.

Then he tried to sit back and force himself to relax.

He swung his feet to the side of the bed and tried to sit again.

He tried to sit, and did at the second try.

If that is not possible, at least try to sit with children while they eat.
