One of my mentors early in my career advised me to call three second violations as infrequently as possible. His premise was that "nobody likes a three second call." Talk to the kids during play and tell them to get out of the paint. Most of the time they simply forget where they are, especially at younger age levels. Keeping the kids moving keeps the clock and the game moving, helping you in that never-ending quest to "get into the flow of the game."

Now, having said that, you have to call it if a kid gets in the paint and camps.
