Every morning my nearly 4 year old DS2 acts like a dinosaur in the playground when dropping off my DS1. He roars constantly and spends the whole time running around and grabbing people. All the older boys know him and goad him into chasing him, whenever there is a big group of boys he is always in the middle of them.
How can I control him, he starts school in September and I think he is getting a reputation already. I don't mind him playing with his friends but don't want him appearing disruptive.
