Wosie is 8 months and Dreama 4 years, and they BOTH still mouth your hands! They are good about it, and don't do it to hurt. It's a playing thing for both of them that I only occasionally feel is obnoxious. But we are always saying "No Bite" especially to Wosie, and I am sure she thinks it is her real name. But as soon as you say it, she stops. She just can't help it. It's like her way to show affection.
