Well simply I teach them to sit or down and wait. Start when they are young and only attempt it when I'm the right frame of mind to be patient. We have lots and lots of failures, someone looks the other way, pulls grass up or simply isn't playing. If I have to keep putting youngsters back the oldies then look bored so I give up. I've also learned that switching the sound off the camera gives me more opportunity to get it right, as with some it's one click and their gone. It's quite funny really if I try and get a pic of an individual the others will push in and sit next to him/her ... Yeah quite a lot of photobombing goes on here these days!
