Cutting a Tooth

Josh has been cranky for the last 2 days and not able to sleep very well at night. We are guessing that a tooth is coming through (Anh's mom has been saying this for about 2 weeks- some kind of intuition). I still can't see/feel anything on his gums but Anh says she can (maybe because of my dulled senses). Hope it pops out quickly. Even though his whimpers are really cute, I think he's not very comfortable.
