Dorian is at the age when every time he sees the camera he stops whatever cute thing he's doing and smiles at the camera. Tristan is at the age when every time he sees a camera he makes a weird face. (I remember when my older brother went through that phase. That was back when you had to buy film and then pay to develop it. My dad would get upset about Alex "ruining" all our pictures with the weird faces he would make).
