Can I really be this old?

Ok, so maybe "old" is the wrong word but I have a 6 year old daughter?!?!?!?  Where did the time go?  I feel like I just had her and was "enjoying", for lack of a better word, the joys of having a newborn...you know, colic, lack of sleep, crazy hormones, all the fun stuff!  Jenna has grown into such a little lady, a diva even.  She is strong-willed and determined (even if it is to just to get under my skin) and she is a wonderful big sister.  Some days she drives me completely nuts but I know the best days are ahead of us still.  I love her with all my heart and wouldn't change her for the world!
