why not threaten to take something she really likes away from her or threaten with time out? i know the word threaten sounds really ugly, but i cant think of a better one at the moment.
when she throws a tantrum, ask her is she wants (favorite movie or toy) when she gets home. if she says yes, then ask her to stop or she'll be banned from it for the rest of the day. its like tiny groundings, if you know what i mean. she doesnt get this or that for the rest of the day. my three year old usually responds to spongebob.
or, if thats too old school for you, then put her in time out. make her sit in the car for three minutes, or a randomly placed chair thats in a boring spot of the house. you have to tell her she will be in time out for 3 minutes, (one minute for however old she is) for throwing a tantrum or doing whatever she did wrong that you dont agree with. you have to make sure to explain everything in detail until she calms down, and try to help her calm down by talking to her in a non-threatening tone and helping her breathe slowly, and make sure to tell her you love her but thats shes being disrespectful to mommy and daddy.
make sure to praise her for sitting still and quiet like a good girl, and remember that she is three and that she wil grow out of it. i know its embarassing, believe me, but you just have to say to yourself that shes your daughter and shes acting her age. if others dont like it then who cares? let them deal with it. you have enought to deal with yourself. haha.
hope something helped. these usually work for me.
