My husband just called me to tell me my little girl's bottle smelled funny (smelled like spit up milk he said). It was milk I pumped last Thursday (4 days ago) and it has been in the fridge ever since. She drank about 2 oz. before he noticed. He pulled another bottle out of the fridge and he said it smelled a lot better. Will she be okay after having drank 2 oz. of smelly milk?
