This sounds like a boy that I have here. I had Child Development come here as there were issues besides his aggressiveness. They decided that he's within the typical level for his age. I would have termed by now if the parents weren't working with me on this. I'm at the point where if I can't see him and I need to be somewhere else in the daycare, I have him follow me until I've completed what I need done. I'll continue on with this for a couple of weeks and hopefully I'll see a change. After shadowing for a couple of days I've discovered that he may not be totally responsible. For instance I caught one girl pushing his hand away so that he couldn't play with the toys. I'm also dealing with another boy that doesn't like to share, so I think there's a few things at play here.
