My 2 1/2 yr old student is very attached to me. He pushes/hits any student that tries to get near me. He follows me where ever I go holding on to my shirt. Sometimes I can't step out the room because he"ll throw a tantrum, because he wants to be with me. He wants to be on top of me at all times. I love him (I love all my student), but his behavior makes me feel like I'm suffocating. Talking to his parent about his behavior didn't help either. I don't know what do to stop this behavior.
