In this day and age, an ipad works great here...with the sound off of course. Also bribes work well but honestly, I geared the kids up well before we had any such event to go to. So many times, children are allowed to go wild with no rules when with the parents or at home and are then expected to act differently in public. It doesn't work that way. Kids can learn early on about limits and what is expected of them. Yes, they will continue to test those limits, but if they don't know them in the first place....I think you get the picture!
