"Setting boundaries is healthy, and respecting them is important." Respect other peoples' boundaries, and their desire for peace and quiet, the ability to enjoy a meal without being interrupted or having to shout while your child sceams and runs around the restaurant, allow the tired mother whos one treat per month is getting a haircut without entertaining hers or someone else's child, allow the person reading their book in the sunshine on a bench to read uninterrupted. Children need to learn they are not the center of the world, even though they are the center of your world. Part of that is teaching manners, how to conduct themselves in public, Your own kid is never as cute as you think they are. I have two, I know we overstayed our welcome more than once in public places and I got up and removed them from the situation rather than cause discomfort to those around us. It's the decent thing to do.
