Mason is 4!!!

My son turns four today. Four. I have been his mother for four whole years. How crazy is that? I can't believe that he is four. Next year he will be five, starting KINDERGARTEN. How is that possible? Yesterday he smiled for the first time. Yesterday, he learned how to crawl, yesterday he learned how to ask for juice, yesterday he "read" me Brown Bear, Brown Bear. How can he be four. At this rate, next week he will be in 7th grade. I can't imagine that. Scary. I need to go. I have to start praying...
