A hypothetical camp where you stay the night that might not ever happen—and wouldn’t happen for eleven months at the soonest.

Encourage her to get other kids to talk about themselves. Tell her it’s okay to just sit nearby (parallel play). It may take a hike but they’ll probably try to include her eventually (maybe not the same day).

Once she gets interaction, tell her “I don’t like that” (being specific is better, but if you’re emotional, “that” is fine) works way better than “please stop” since it eliminates any power struggle when there’s a disagreement. Other statements like “May I have a turn?” are helpful. Most six year olds understand taking turns if it’s explicitly stated.

You included a lot of the Disney/Pixar I would have suggested but OP had said they weren’t too keen on Disney. I feel the ones you listed do have healthy gender representation, so I’m glad you included them.

I haven’t watched it enough to know if it has healthy portrayal of gender.

Yeah, it works well from parent to child or from child to parent, too.

Teaching kids to say “I don’t like what you’re doing” (or the specific action) to each other instead of “stop” makes their interactions far more peaceful. It avoids a power struggle where the person doing the action has to decide whether to do what the other said (“stop”). Instead, they now have info they can use when deciding if they want to accommodate the other’s opinion or if they prefer to be a jerk.
