I have a 3 year old (he just turned three last month), and for the most part, he is a lovable, kind, and really sweet little boy. He attends daycare during the week, and he behaves very well there, gets along great with the other kids, and no issues have been raised. He seems to be progressing normally in his language development, and he can sit down and let me read him a story, or play with his play dough/train set etc. But then occasionally he thinks it's hilarious to throw his toys around, and then run up to us and hit us (not in an aggressive way, he just laughs thinking it's funny). When we try and reprimand him, he just laughs. When he is in this mindset, I have no idea how to control him. I don't want to resort to shouting at him (which doesn't work anyway), but I'm at a loss as to how to get him to calm down in case he breaks something or hurts himself. Any helpful advice would be appreciated!
