Wow, my 14 month old just started this this week. More teeth are coming in, top and bottom, by the day. I'm glad you asked, and for the responses. When she does it, I put my finger on her lips and say, "No". Now, I will leave her alone, and try not to get too annoyed with the sound of it. It sounds like she's doing major damage, but I'm glad she's not.
