I work in a multi-age classroom and the range varies from 2.75 years - just turned 5... and our youngest is having a tough time behaving. Everyday, from the moment he's no longer alone in the morning, he's constantly mimicking other children's behavior, and most of the time it's unwanted behavior. I've tried to explain to him that he's an original, talented, unique little boy and can do things that only he can do... so that he may start acting like himself, but it doesn't seem to have much of a result. What's strange is that at the start of school, he was perfectly behaved and did his own thing with children, had no problem sharing, didn't fidget during circle time... and over the last month he's been increasingly getting worse. And I do realize that mimicking behavior is a way that children learn, but how to I curb the bad behavior from being learned and mimicked? It's reached the point where it disrupts the class and causes problems for other children... I also explain to the other children that he does what he sees and so they must not encourage him to do these behaviors (like crawl under the table or roll around in the blocks...). He also had trouble sharing and taking turns... is this just an age thing? or is something going on where I can help him? I've also tried the thinking table where we have books to look at that have to do with good manners and being a good friend, so that he may calm down and remember what he needs to say if he wants to play with someone else's toy... But it doesn't seem to stick because a few minutes later, he's copying someone's phrase, or chasing someone or taking their toys away without asking. Anywho... sorry for the length, but I really need some advice on how to help him out. Thanks!
