Stay this way forEVER: 365 day 162

Another school year almost finished and I realize just how much she's growing up and changing. I know this is very selfish of me but I wish she would stay this age forever--she is the cutest, most innocent and loving girl. Every morning when she wakes up & every night before she goes to bed she gives me a big hug and a kiss. I wonder how long that will last. Why do things have to change?
