I had some unthawed breast milk in the fridge since yesterday. I didn’t realize that I had to use it within a certain time. He only drank about an oz of it without refusing or squirming like it was bad. But did projectile vomit about 20 minutes later after burping and having a dirty diaper. So not sure if it was bad or possibly going bad. Praying he is fine and that was the only vomiting he does bc he doesn’t normally do that unless I give him formula.
