a bump in the road

Shane is well liked by all his teachers.  Ye,t he has moments where he can't get it together.  I'm not giving up.  I am trying this new belt called the "miracle Belt"  I've never used it before and am hoping for the best.  It is suppose to ground them and help them with focus.  It's weighted so I'm hoping that it does keep him in line literally.  The teacher said that he still stands up a lot during class and can not seem to stay in line.  ahhhh!  Very frustrating and on top of that he has consistently misbehaved and he's very baligerant (not sure how to spell)  He stamps his foot now and has kicked both me and his father.  I personally don't take that shit.  So I have retaliated. Nothing harsh. But I'm trying to teach him to keep his anger in check.  Because any person getting hit by him he will get hit back.  It annoys him more than anything else.  But I've gotten my point across.  I'm tired of the disrespect and I want him to stop.  Just stop.  It hurts my feelings and at the same time it makes me angry and question what am I doing to make this happen.  I pray I can come up with a better alternative.  Wish me luck... So far not so good.  Oh and the kitten is a love.  I'm so attached to her now and of course I'm doing everything.  UGH!  Am I that predictable?
