First day of 4th and 1st grade

It's a bitter sweet feeling that my kids are back in school. Bitter being that the summer went way too fast and that my kids are growing up so fast. 4th and 1st grades already. WOW. It just seems like Riley and Keegan were just learning how to write their names and  tie their shoes. Its seems like Carson and Cooper were just learning to walk and talk. What happened to my babies?  The sweetness of it all is that the fighting has seized! FINALLY! But most of all,  these years are going by so fast. I need to step back, take a deep breath and enjoy what I have, because I'm going to miss this if I don't.  (If you haven't heard the song, You're gonna miss this by Trace Adkins...Grab a box of kleenex and be ready to shed a few tears.)
