We use time out or even removing yourself to a calm place to settle down here.

It's definately something that needs to be adjusted to suit the age of the child and even the temprement but me personaly i feel there needs to be a point where some form of consequences are learnt.

With DS1 i don't know at what age i started using it but i remember the beginnings of 3 being a real challenge so it might have been around this stage. I would warn him about his behaviour and and that if he didn't stop he would be spending a few min in his room. If it got to that point i would put him in this room and when i went to bring him back out we'd have a little chat and a hug. I try to be firm and clearn in what is happening and why.

DS2 is 3 in March in this second part of the year there have been a few occasions where i have done it with him. He has learnt a lot earlier about pushing the boundries from his big brother. He too knows how to push his brothers 'buttons' and create issues to the point where i'm dealing with two children who just will not back down.

In the taking yourself off to a calm place option sometimes DS1 gets extemely frustrated at his little brother and if things don't go his way so i have tried to get him to learn to remove himself and go away to a quiet place until he calms down and feels better. He's got a really quick temper like his dad
