My mom babysat for me tonight, I had pumped milk a little bit ago. Well long story short, it had expired by a day or so, like a week ago so when I seen that I popped it in the freezer. I had a weird "mommy sense" and almost called her to not feed it to him. He only ate about 2oz of the bottle & didnt want anymore. I got home and fed him breast for like 5 min max & we were out for the night. Well he woke up about an hour into sleep, two hours after bottle & threw up. He got sick a good amount but not too bad. He wanted to nurse immediately following getting sick, I bathed him and cuddled some before feeding him about 2 minutes and he was asleep again. Should he be ok? Will he get sick again? Anything like this happen to any other moms? Breast feeding storage tips? Thanks lady's & gents!
