Just Flog them, lol I'm just joking, lol Ahhh the joys of toddler years, I think it shouldn't be called the teribble twos as I think it really starts at 18months and goes to about 3 and a half. I agree with what everyone is saying here. It is very important to be firm and consistent with disapline and to get down to their level. Eye contact is also important. If they turn away from you turn them around hold their hands look them in the eye and give them the Actions/cosequences talk "If you climb up onto the table you will fall and hurt yourself". I always use a very firm no and usually a Uh Uh will do if they are thinking about doing something thaty they shouldn't do. Also with disapline it is very very important to be united in your disapline. THey work out very quickly how to play parents off against each other if they are not on the same wavelength.
