Do We Have Mice?

William has four bottom teeth and one top tooth. His other top tooth is just coming in and he has been biting anything and everything he can get to his mouth. Paul and I walked to Co-op tonite to get a few groceries. Will was being fussy so we gave him a box of Rice Thins to shake and play with on the way home. When we got home, we discovered that he was eating his way through the box, he swallowed all the cardboard too. Do we have mice??? No, we have William :o)
