A boy who believes in Tooth fairies

So, Karthik's front two teeth finally fell in the last couple of days. The adult teeth started growing and it managed to push those two baby teeth off. Last year he had couple of lower baby tooth fall and at that time, he was convinced without a doubt that Tooth fairies are real. This time though, his friends had told him that its not the tooth fairy, its only the parents who give them coins and throw the teeth in the dustbin. He asked me if it was true and I ofcourse said, no they are for real, probably its different in each home. He was so convinced and planned to keep his tooth under the pillow. Thanks to my almost 12 year old who lets him have his innocence and smiles when he asks her if I am telling him the truth. I know many of the older siblings who spoil the fun for the little ones. On the day of the first tooth falling, he loses the tooth, cries his heart out. I told him to write a letter and he writes saying, my tooth fell off, but I lost it. Sorry, I will be responsible. He wakes up, finds a $5 note under his pillow and is so happy to tell me that the tooth fairy appreciates his honesty and leaves him more money than usual $2. The next day he managed to pull out the other tooth and yet again, loses it. He made me search the whole home for it and ended up again writing a sorry letter. So the tooth fairy left him a note that she loves him so much and his tooth will grow up to be a beautiful tree, just like him. He wakes up in the morning and is re-reading the letter and is so happy! I do know that not many 8 year olds are that innocent and I appreciate it so much! His toothless smile is heaven. Soon he will grow up and not be this childish anymore, but I relish every single thing he does, so pure hearted and innocent! Please dont grow up too fast baby!
