This is my first time posting, although I've been reading the posts for a while and have found them very helpful (so thanks!).
I know that thawed breastmilk is good in the fridge for up to 24 hours from when it finishes thawing. The resources I've checked, however, seem to suggest that it will take around 12 hrs to thaw. I put two 3-oz. bottles in our fridge last night, and they still are mostly frozen. I'm afraid it may take up to 36 hours for them to thaw completely. Is the milk still good, or is it problematic that some of the milk in those bottles will have been thawed for over 24 hours? Is the 24-hour recommendation related to bacteria forming in the bottles, or to a weakening of the immunological benefits of breastmilk?
