M.,
contrary to what society urges parents to believe, I do not think that 'temper tantrums' are wrong or bad. We are taught that as parents we should lead our children and have control instead of having a respectful partnership with our children. When my two year old becomes visibilly upset I sit down near him letting him know that I am there for him, and wait for him to calm down. I see a 'temper tantrum' as my sons cue to me that there has been a disconect. He is looking for attention, but not in a bad way, more like he is needing something from me such as to sit down and cuddle for a few min, to read some books together, nurse, or sing a song. Putting your child in a time out or in there room for being upset is sending the message that it is not okay to be visibily upset and that you are essentially shunning them for showing negative emotions.
Try looking at what message your child is trying to send you! I found the writings by Alfie Kohn very helpful with this. His website is alfiekohn.org.
Good luck and happy parenting!
