Breastmilk vomit smell

Mine is no smell after refrigerated but always smells like vomit when the milk wet my bra especially during letdown or when my breasts are full and I have no time or forgot to pump. I read that it's ok. My nb does not gag or vomit but still drinks it. Found this on Google. Lipase is an enzyme in human milk that breaks down the milk fats so baby can easily digest it. Mothers have found that an excess of this enzyme can cause the milk to smell or taste sour or soapy, even though all storage guidelines have been followed.
