When photographing children, you never know what you'll get.
Some sit still, in the spot the adult placed them, while others wriggle and squirm and refuse to stay still.
Some of the children will (maybe) look at the camera and smile while others won't give the camera the time of day and will look everywhere BUT at the camera!
But, one thing you can be SURE of, is behind the camera is a gaggle of adults yelling, "CHEESE!" "LOOK AT THE CAMERA!" "SIT DOWN!" "STOP MOVING!" Yes, photographing children is an adventure and the chances of ending up with a photo where ALL children are looking at the camera and smiling is pretty much impossible. At least it is with these 7! (But aren't they cute anyway?)
