What should i deal with 3 years old girl when she throw tantrums?

Here is an useful article on how to discipline your child (at various ages): http://sg.theasianparent.com/smart-ways-to-discipline-your-child-at-every-age/ For a three-year old, the article suggested: - explaining to your child about what he/she has done wrong - giving time out - removing your child from the situation - withholding privileges (favourity toy, television time etc) for his/her misbehavior and a couple more from my sister-in-law (who currently is handling my three-year old nephew): - gives plenty of praises for good behaviour - ignore whining or sulking behaviour (by not responding at all)
