J.,
My husband thought that was the way to get our daughter to stop biting. It was not the way, and it only mad matters worse.
what did finally work was that when she did bite someone, we paid all the attention to the person that she did this to and then told her that biting hurts and don't do it anymore.
She did stop doing that a couple weeks later. Now in daycare and getting the ohther end of her old habit she stopped dong it.
The reason from most biting is due to not being able to channel thier feelings or need to communicate. This is usually a stage, and if you work it right they will stop.
My duaghter was close to getting kicked out of her daycare for this bad habit and she did bite me many times. I can understand how upset you must be with this habit. Most people are understanding about it the first time, then after thtat it gets ugly. I had several moms upset with me and my daugher. They are just now starting to talk to me again and include my daugher in play groups.
I wish you all the luck in the world with getting this stopped. I understand how being a mom is hard. I have a bad temper and there have been a couple times when I almost lost it. Just step back and count or just listen to some music you like and try to relax an minu te, then go back and try again.
