My baby is already 6 years old, but I can remember tantrum horror like it was yesterday. I had some advice from my mother; my favorite was time-outs...sparingly. Depending on the child, using a time-out occasionally, beginning at about the age of 18 months, may help her manage feelings better when she has a tantrum. A time-out can be helpful when your child's tantrum is especially intense and other techniques aren't working.
Placing your child in a quiet, or – better yet – boring spot for a brief period (about one minute per year of his age) can be a good lesson in self-soothing. Also there are videos online on how to talk with your toddler correctly. Most of them are rubbish, but few are gold. I found this one but it would be against the rules to post a url advertising it helpful and this one is not bad too but again, I'm not going to join and then start breaking all your rules.
