Gabriel's Actions

Lately, Gabriel has begun to get more and more aggressive. He has even started throwing temper tantrums by crying and throwing down things that happen to be in his hands and storming off. I thought most of this was just at home, but I have also seen some of it when I arrive early for pick up and watch Gabriel playing on the playground. I have always tried to instill in him the use of his words to express his frustrations, but lately he seems to be over come with frustration or anger and acts out. I'm not sure how to handle it except to keep reminding him to use his words and give him time away from the problem by sending him to his room until he is calm. I just don't want to talk him to death, then I am sure he won't "get it". I also need to talk with his teacher and see how often he reacts this way at school. It may still occur more often here and I just happen to see it on the occasions I am early. There have been so many changes, with Matt traveling and school and us expecting a new baby, within the past couple of months I guess I'm not completely surprised with the behavior though. I just hope we can find a good way of dealing with the problem.
