I have two boys, ages 5 and 2. My 5 year old just started Kindergarten this year. He has had his issues with jealousy, hands on, anger issues, etc. He had been doing a lot better over the summer, but as soon as school started he turned into a monster! He is currently seeing a therapist to deal with these issues.
He is very hands on at school touching friends and throwing rocks during recess. He has a very hard time at recess because he gets himself into trouble.
Then, when he gets off the bus all he does is whine and cry and it just grates my nerves. I give him a snack and a drink then we work on writing his letters, math, art, play, etc. Then, as soon as I say we have to stop he starts screaming and yelling at me and making my life miserable after we just spent a wonderful hour or two doing fun stuff.
