Yes same thing here! I thought it was just me. I think it has to do with boredom. DS starts big school in feb and he really needs it. I've been at a loss at how to deal with him. Putting him in his room is the only thing that seems to help and we've started a reward chart of fireman Sam (his favorite).

He has been talking back, being uncooperative, throwing tantrums, hitting and can't entertain himself at all. Im hoping his behaviour improves once he starts school. He was held back as he needed lots of help with fine motor but emotionally he has been ready for awhile.
