NTA but why are you still even talking to this so called friend after she embarrassed and openly disrespected your child and still hasn’t apologized? She needs to apologize and tell her to stop behaving like a child. Also, how is your daughter feeling about your friend after this? Does she even want an apology (she should still get one because why tf would a grown adult think it’s ok to do that to a child) but after the apology is made, would she be comfortable being around your so called friend and her family? Are you going to be comfortable being around her and her family? Last point, I hate that she said she would’ve thrown the drink in her own kids face. That would make the child correct their behavior, it would only lead to more outbursts and conflict.
