Our tanties are mega here too. Phoebe hasn't cottoned on to 'sorry' yet - we've only recently started with 'thank you'! (Late bloomer as far as manners are concerned, LOL! Although she does say 'pardon me' after she burps which is more than her father does.)
She doesn't throw things either, unless you count herself (ie, in the midst of the banshee-esque screeching she will propel herself backwards onto the floor). This is done with gay abandon on carpeted floors, however it is somewhat more gingerly on the lino floor. Her screaming is really quite disturbing. The only way I need to deal with it though is to ignore - I stay with her but I don't pay her any attention until she has settled down. It would be different though if she were hurting me/others though. We would do time out here too, probably sitting in a chair. Natalie however is taken to her room for time-outs these days, but she used to stay on the chair when she was this young.
She's actually having tantrums at bedtime! Nothing in her routine has changed and she is delightful whilst we are brushing teeth, reading a story and saying goodnight to the three owls on her wall but then as soon as you get near her bed she gets quite irate. It's sooooo hard - not sure what we can do about it. It's obvious she doesn't want to go to bed, and perhaps she's overtired, but it's getting very draining and the tanty goes on for quite a while. I thought we were done with bedtime difficulties but they've stepped up a notch once again.
