5 year old caught licking the floor in class, could use some advice

Hey folks.My 5 year old boy started Kindergarten this year, and has had a slate of issues that caused the teacher & principal to call me, including:Screaming bloody murder anytime he’s felt wronged or had his foot caught in a part of the playground. (Teacher has told me it has been to the point where it has scared other children)being too handsy with other classmates.hitting! (This one surprised me)Some of this hasn’t surprised me. He’s been a delicate child ever since his toddler days. The screaming and being too handsy part has been a challenge at daycare whenever they moved him to a new teacher or he had a big change there. It’s not behavior we’ve witnessed at home, although he only has one sibling (an older brother), and with that there’s less opportunity for confrontation.But this latest one gobsmacked me. I got a call from his teacher yesterday afternoon letting me know that while they were all on the floor with her reading a story, she caught him lying down behind everyone LICKING THE FLOOR. She didn’t bring attention to it when it happened, but she asked after “what were you doing?” And he acted like with her that he didn’t understand what she was asking him about.I had a talk with him last night, and he eventually admitted to doing it, I asked him not to do it again and he agreed (although with him it’s tough to tell whether he’ll truly understand he can’t do it anymore), but I’m just waiting for the next shoe to drop and hear about what he did next.I’m at a loss of what could be causing this severe a trend of behavior, but ESPECIALLY what’d compel him to lick the floor. Beyond the inherent health concerns, it’s just completely unlike him to behave like that, and I feel like my wife & I have been trying to work out what could be contributing to that behavior at home and coming up empty handed cause he doesn’t DO those things at home.So I post this hoping some of y’all might have some thoughts or perspective. It’s probably not as dire as it sounds in my head, but I’ve been concerned about the larger trend line punctuated by this incident since starting kindergarten.Thanks! via /r/Parenting https://ift.tt/33EHxhA
