I have a "handful" as well that has several major tantrums a day. I generally choose to ignore them as well --- I do not want to reward her with attention. Also, trying to diffuse the situation only seems to escalate it. At times I feel bad as well but what are the alternatives? I refuse to walk on eggshells or give in to her to avoid the tantrums (like her parents do). I find cocktails on Friday night helpful!
