LOL, "Pez-Head" ! I've had 4 deaf kids over the years, currently 3. The first girl, a rescue was very private and leery, the others I got as kits. The 3 I got as kits all have done this and still do even though 1 is a senior, 1 is 3 1/2 and the other 9months. I have always thought it's a n alternate sensation for them. [Posted in FML 5721]
