My DD is 18 months and i was told by my CHN to either distract or ignore. I have found for me i tell her "mummy gets sad when you behave like that so i'm not going to stand and watch you when you've finished i'll be ..............(in my room, kitchen etc) she likes to be with me so she soon picks herself up and comes to find me i leave her be for a min or 2 if she is still crying but if not or as soon as she stops i will explain why she was told No or whatever the reason for the tantrum was. We had a couple of really bad ones with hiting and lashing out and this seems to be working so far..HTH
