well, im a relatively young guy with lots of much younger half/step siblings. they're so much smaller that its really more like a parent child relationship.

anyway, what works for me when the kids dont obey is to stop them from moving around, make them face me and look me in the eye, and then apply a slight pressure to the shoulder muscle (enough to let them know that I'm not joking, but not enough to hurt them) and then tell them what they need to do, perhaps taking them to the place that they need to do it.

their father will tell them to do something, and they usually wont obey until he starts screaming at them.

I never raise my voice, I tell them once and if they dont obey, I employ the aforementioned method. it seems very effective on these particular children.

after reading the other replies, it may seem as though what I'm saying is irrelevant, but the general idea is the same. be firm and dont let your kids roll you over. always follow up with what you say you're going to do.
