I’m a parent and do not agree with this approach. Everyone should behave in public - and kids should practice so they can learn. At home, my kids get to behave like animals and we do things where they can behave like kids, like trampoline park, zoo, the arcade, etc. When we are out at places where the kids should behave, we bring them iPads and headphones so they are able to make it through the activity. But it is just rude to let your kid intrude and ruin a dinner, museum, movie, etc for others.
