My daughter has had similiar problems every year since kindergarten. She's going into 4th grade this year. Must be something about 2nd grade, she had the WORST time that year. She wouldn't get on the bus to go to school, wouldn't get out of the van when I had to then bring her, was a "frequent flyer" at the nurse, wouldn't want to be in class, once yelled at the top of her voice to the teacher that she wanted to go home, on and on it went. It got bad...she ended up being so out of control she was hospitalized at a behavioral health hospital for 2 weeks inpatient and 2 weeks outpatient. I tell this so you know that I KNOW where you are coming from. Most important thing: daily communication with teacher right now. Call the teacher and discuss the situation. Things that worked for us: start small with earning priviliges. If he has a GREAT day at school (you know this because teacher sends home a post it note w/ a smily face or some other quick type communication) then the next day, choose a reward that involves school: he gets a ride to/from school instead of the bus (we only do rides home, otherwise you have the battle of not wanting to get out of mom's car to go to school), mom or dad going in to eat lunch w/ your son (this again, requires separation at school which is a potential disaster. I'd save this for a few weeks or whenever he is doing great w/ coping several days in a row.) After a few days of good days and daily or every other day rewards, start spacing out the rewards to be once a week. Also, I had a treat bag, each day that was a good day (per the teacher, not your son) my daughter was given something from a special bag I had (dollar store stuff, garage sale finds, etc) Of course there's doing a chart with a sticker for each day. After a great week each day M-F, we might do something special as a reward, trip to get ice cream, etc. Communication w/ teacher is critical! My daughter is doing MUCH better now! She starts school next week. What we do to help get her acclimated is have her go in and help the teacher before school starts. It is billed as "your new teacher called and asked if you'd like to help her in the room, etc. This helps her to build a relationship with teacher ahead of time which is huge. Think about that for next year! Or even, just maybe see if your son could stay after school 1 day to spend some time helping, it may really help him to get comfortable w/ room and teacher when he's there w/o class. Best of luck, I've been there, I feel your pain! Hope my suggestions help!
