teething...

Is anyone else's LO teething? My LO is 15 weeks and I have finally decided that he could possibly be teething. At first he was just discovering his hands, but now it seems like he is chomping down to relieve pain! He cries uncontrollably sometimes and it is hard to calm him down. This is very unlike him. If your LO is teething can anyone post a picture so I can see what the gums would look like. Thanks!
