Missing the tooth makes him speak differently and whistle unexpectedly at times which is pretty entertaining. Gray has also discovered he can stick things in the gap between his teeth (like food or straws) and never tires of the trick.
The tooth fairy brought a stack of quarters with these three small crystals on top. Gray loved them and quickly put them in his treasure box. I keep trying to convince the tooth fairy to pace himself, but I think he's having too much fun. Only 17 more teeth to go!
