Enjoy every second of having a 6 year old girl.
Day before yesterday I got up early and was doing some work on my computer. I was working with some directories when I chanced upon some old songs that I had loaded into a folder of her favorite songs.
I hadn't heard them in years, so I listened to snippets of Barney songs, some old Disney songs, etc. By the time, I played "Once Upon a December" from the Anastasia movie, I was bawling like a baby, alone in the dark of my office.
She turned 13 two weeks ago. I love her more than life just as she is, but I will always miss that little 4 - 9 year old bundle of sweetness.
Same here. When they were young you were the most intelligent being on earth, but when they hit double digits it's amazing you can even breath correctly. I'm told in a couple decades it'll get better for a few weeks before they put you in a nursing home.
