My kid finally gets excited about going to the cinema, so we go,and he ends up having difficulty regulating himself there…I guess I better scoop him up and fuck off back to the cave we crawled out of.

If they are doing something really disruptive like crying for extended periods of time just remove them from the setting for long enough to regulate themselves and go back in. Keeping them in a setting where they can’t regulate themselves for extended periods of time is counterproductive. I stepped out into the hall with my klddo to get away from the loud noise and bright screen so she could get herself under control a lot of times, and eventually she figured out how to regulate herself in those same situations.

Now if people are shitty because the kiddo is doing regular kid things or because they were disruptive for a short period of time then they can go eat a turd.
