Wow I can't believe it

I cant believe our daughter will be 5 weeks old tomorrow.. It seems like I just had her the other day.. She is starting to smile when you rub her checks or do patty cake with her...She is starting to stay up longer during the day and sleep more at night.. She ways 8 pounds 8 ounces and is 20 inches long..Her eyes are still deep blue (praying that they will stay like that).. Little nathan seems to be doing a little better with her. Before I know it both of my babies will be in school, why does the time fly by soooo quickly once you hit 21 and then really quick when you have your own babies????
