This sentence is really confusing for me. I've checked Collins, Oxford, Cambridge, urban… dictionaries, no such collocations.
my guess is "the wind changed" means she senses something bad might happen?? ( so wind means bad things??) if so, or not, then why the face "stick "?? does "stick" mean her expression "fixed", not moving, and why?
and why on earth "mum would use this kind of face to warn me"?? what kind face? is it some kind of face a parent gives to a child who makes a mistake?
here is the sentence:
Her daughter, curled up next to her on the sofa, just glowered—the kind of face Mum used to warn me would stick in place if the wind changed.
the context of the above sentence is: the daughter glowered at "me"–––– a paid carer for the daughter's quadriplegia brother. after "me" suggesting some plan to help the brother, a plan which requires their approval and their financial support.
