If this is a sudden change as you say, IME theres usually a reason. I would be asking the parents if there have been any changes in his day to day life/routine. Is m or d working late and seeing less of him, has he gone into a big boy bed/given up his soother or blankie, is there a new sibling, is he involved in a new activity with a new group of kids etc etc. Theres usually a reason and that way you may be able to address this cause at the route of the problem.

Also IMO, I wouldn't give timeout in the exersaucer as he is being forced to stay in one spot where as time out in a corner or a particular spot in the room away from the action gives him the choice to get up, so if you are on top of his time out and make him stay in his spot for his time out, and keep putting him back if he gets up, then he will learn to make a better choice even for just this 1 or 2 minutes on time out and he will realize that he has control of the consequences, rather than just confining him. I would also be very consistant with time outs EVERY TIME, even if he hits 10 times a day. Also making him apologise to the victim and give hugs to show caring and loving behaviour.

Good Luck, these things take lots of patience and commitment to work through. I hope you get your loveing caring dcb back soon
