Kids growing up too fast

Today we went to the nice park (Jacksonville Commons). Kaitlin was swing all by herself. She is getting really big too fast. It seem like yesterday that she was just a baby. The other day she said that she wanted to be 16. I'm not ready for all this. I really want her to stay my baby girl forever. I know that we have to let go sometime but I'm not ready. These kids these days are just growing up really fast.
