Hello, I teach 4s this year and I have a student who behaves extremely well in the classroom. I have noticed that when his mom/dad arrive to pick him up, he starts to misbehave and do things that he wouldn't do during school hours (such as kicking the wall, throwing classroom items...). He listens to me during school. But when his mom/dad is present, he does not listen to me. In the classroom, I re-enforce discipline by giving positive verbal reinforcement and modeling behavior. So, I'm not sure if it's me or something else. Please help!
