FIB Forgive your sister please. God knows if I were in her shoes, there'd be "words"...to be sure. I mean, I don't even know your w, (though I sure feel I do) and I want to slap her silly. I think I'd have called her a "cruel, emotionally unstable narcissist", but that is only if I was expecting the call, and your poor sister wasn't. I feel for your sister btw. How is she feeling about it all now? Bleh!
So, what's worse for the kids? A private rebuke from your sister to your stbxw, or your w's outbursts in front of the kids, to you? Um, by far, the latter. Only a person blind to their own failings and shortcomings and repeated misbehavior, would fail to see that. Too bad your stbxw falls into that category. Geez, her and her tantrums. You'd think even she'd tire of them. They exhaust most 3 year olds.
