Skyuse ... certainly entitled to your opinion based on your experience with children and what works in your group ... it just sounded like time out was not working for the OP's biter which is why I weighed in and offered her a different way to look at the problem that might get her a more positive solution and reduce her stress

Most of my career I have had to work in settings where time out or any form of 'punishment' was forbidden by staff .... which has required/allowed me to hone other ways to manage and correct behavior in children by coming at it from the positive position of them learning and supporting the child through logical consequences to make better choices verses punishing them when they do not .... the fact is that while we might all share the same goal for children's behavior there are 100's of ways to achieve it ... there is no one right one size fits all way and often in our programs we need to have a a good 1/2 dozen behavior and guidance approaches depending on the personality and temperament of the children in our care

I also agree that there needs to be lots of discussion on biting or aggression in general being wrong and why and what to do about it with the entire group when or if it rears it head with them ... both the biter and the victims ... we totally needed to help the biter learn better choices in that heat of the moment above 'no biting' because that is not enough they need to know WHAT TO DO and we need to help the victims learn how to better resolve conflict and engage in play so that 'frustration' does not arise in the first place .... this is what the 'play invitations' I mentioned are intended to do ...they promote those social skills to be developed via chances to practice in a supported environment when I am there to observe and step in if needed before aggression occurs in the first place ~ giving them the words/gestures and so forth to resolve conflict acceptably.

Other venues for this are at small group / circle time .... using puppets to role model 'conflict arising' and having the children help to resolve it with the puppets through role play ... by practicing 'biting/hitting/etc' at times of the day when no one has actually been hurt and there are no emotions involved of actually having had your own toy or what not taken allows children to actually 'absorb' the information for future times and grasp the messages you are intending to pass along to help them truly grasp concepts of 'right and wrong' enough to over power that impulse of the moment to 'protect' oneself through a fight instinct!
