Can mommy breast milk burn my baby?

My mil said my breast milk can burn my baby if I leave my nipple near him. (Example) last night he was eating and he fell asleep and put his head back my nipple was on his cheek for a few mins and my mil said. Oh you don’t know your breast milk can burn him if you leave it on? I was like no🤨 anyways I’m thinking she means irritation ?? But it’s not like I was just gonna leave it there for hours.
