I have two boys, 23 and 13, and I do not know where the time has went. In a blink of an eye they grew up, or are growing up. Please take advantage of all the special moments you get, like the diaper changes, the chase games, the cartoons and even taking them in when they nap, because it goes by fast and the next thing you know you are watching them graduate school or hearing about their engagement.
You have a lovely family so go make some memories my friend.
