I bought the book the Happiest Toddler on the Block and it talks about how to handle a tantrum. You shouldn't ignore it or speak to your child calmly. You should mimic their tone and say what you think they're trying to say to you in short words or phrases. ONce you get his attention, offer him something else.
About 2 months ago she'd throw a tantrum for everything and after using it for a few weeks, she rarely throws a tantrum.
Like if she didn't want me to put on her diaper. She'd throw a fit and I'd say almost as loud as she was with tight fights and facial expressions, "NO DIAPER! NO DIAPER! I WANT OUT, OUT, OUT!" It was enough to make her stop and wonder what the hell was wrong with me and it showed her that I understood what she was trying to say and I respected what she was trying to say.
Then whne she was calm, I'd say in a calm voice, "But mommy has to put it on and look, I'm all done!" Then I'd hug her and we'd play or something.
