Hi M.,
The less you focus on the unwanted behavior, the more likely it is your son will stop. Kids love attention so much that they'll even go for negative attention. That being said, at about four, my son developed this awful habit of putting his entire bottom lip in his mouth and ligtly chewing the skin below it with his upper teeth. He gave himself this nasty smile-shaped red line on his chin that started to get rashy. My husband and I showed him the line and rash in the mirror and explained to him how he was making it happen. Then I slathered Neosporin all over his chin to help it heal (which it did). He was not happy with the Neosporin at all! When I realized that, all I had to do was say, "I'll get you some Neosporin so that you don't get a rash," and we would plead with me not to and his lip would come right out of his mouth and stay out. I always said this as though I just wanted to be helpful, not like I was getting the stuff as a punishment, but I was adamant about applying it. He still bites or sucks on his lower lip a little when he is feeling nervous or unsure, but not enough to cause any rashes or chapping. I'm taking what I can get! We'll deal with the Neosporin phobia down the line I suppose :)
