For the past weeks Wawa has decided to be my sergeant. Whenever I tell anyone of my girls to behave, he reinforces the order by chasing them. My girls will tolerate his bullying up to a certain point, then turn on him. Of course, he won't back down so it becomes a noisy argument. No serious fights because after a while they stop and separate. Should I let it be or avoid scolding the girls infront of Wawa? Or should I discourage my boy from overdoing his "bouncer" role?
