It's too soon!

So the last couple of weeks Wesson has been really fussy, and everyone told me he might be teething. So we kept feeling his gums and watching to see if they got red and swollen. They got a little swollen but not much so we thought that the teeth were just moving around. Then as of Friday he stopped being fussy and was his happy self again. Back to sleeping regular and everything. Well, I was at young woman's last night and was feeding him when I realized that he has a tooth sticking up! It's too small to get a picture, but i will post some when you can see it. Then during the night he woke up at 3am and was just screaming. We tried everything to calm him down. We gave him Tylenol and just waited for it to take affect. Then this morning he has a tooth sticking out the top! Man! this is not good. I do not look forward to feeding him now. He is only five months! There should be a rule about breastfeeding babies not getting teeth until they are 10 months. I have a feeling he is going to be a biter! Ouch! Not good!
