For our regular 1st Innings sessions – yes parents are asked to stay. At regular 2nd innings sessions parents are asked to stay on site but don’t necessarily have to stay and watch in the hall/gym. Quite often there are viewing galleries where parents can watch from a distance.
At Camps, parents generally leave but we have no problem with parents staying for some or all of the day. At camps Kids generally settle better if their parents leave when the activities start.
