Any 3 year olds placed in a program of 4-5 year olds are going to look poorly behaved. Three year olds are not going to act like 4-5 year olds. They need a program that is geared to their age and ability. If they are being plopping into a different room, with different children, different teachers, different expectations then they NEED a teacher that can guide them and have patience with them. It is unfair to expect them to just show up, sit down and be quiet. Maybe they need to pee so often because they are stressed with being in a program they are too young for and know they cannot meet your expectations.
