I need some advice from my fellow preschool teachers! We all know whining comes with the territory to some degree, but I have one kid (3 years old) who is the WORST!!! - Someone has a toy he wants: he whines - He hits someone who then in turn does something to him: he whines - He's asked to leave the computer because the timer went off so it is another friend's turn: he whines - He needs to leave circle time/sit down because he's misbehaving: he whines You get the picture. It's constant, every day. Definitely seems like this is how he gets his way at home. Doesn't seem like anything I try to do works. Any tips for curbing the constant whining?
