Time Flies

I registered Sleeping Beauty (AKA "Bebe") for Kindergarten last week.  I am so sad and happy at the same time.  She hugged me when I told her she was signed up.  She has been waiting for "Big Kid School" for three years.  :)  She promised to "remain a baby"  and then to "remain a toddler" and now look!  She is five and will be in school every day in August.  How does this happen??
