Are there any to follow? I have never gone trick or treating before with my kids (3 and 6). We used to live in an area where this really wasn't a thing, but have now moved and it's possible. I don't know if there is an etiquette I need to know about? It will only be the two of then (and me). I assume it would be OK to knock on people's door if they have halloween decorations out, and avoid those that don't. Or do people not do a door to door halloween now? Is it just shops (don't want to do that)? What time would you go out with them given their ages? Thanks!
