Joey lost his first tooth!!!

My son lost his first tooth lastnight. I can't believe it, it's too early to start losing teeth. Well he got his first tooth at 3 months, and had a mouthful by the time he turned 1, so I guess I shouldn't be surprised. The week before Christmas I had my neices over for the night, and Kaytlyn had 2 teeth that were about to come out. She lost one that evening and the other the next day. Joey had told me "Mommy I have a loose tooth too" I said to him "No baby, you are too little to lose your teeth" Well, while we were in Merced I was brushing his teeth, he normally brushes his own teeth, and I saw that he had another tooth growing in back of his bottom tooth. I said "Oh my gosh, you have another tooth coming in" His response to me was "I told you I had a loose tooth, and you didn't believe me did you" Of course I want to cry (but didn't). He then showed me how his tooth was wiggely. I was lost for words other than "Mommy is sorry" He didn't let me forget either that I didn't believe that he had a loose tooth. Who would of thought that a 4 year old would start getting their big teeth. He finally pulled it out last night and put it under his pillow for the tooth fairy!!! It was sooo cute how proud he was of his loose tooth and showed anyone who would look.
