I have been pumping and freezing milk for the past 5 months to prepare for my return to work. My LO just started daycare this week and we started dipping into the frozen stash. When using bottles of fresh milk, she has no issues. However I noticed that she wasn't taking the frozen milk bottles well at all. Fighting and maybe getting in an ounce. She did finally take one at the end of the day, but basically because she was so hungry. When preparing her bottles tonight, I happened to smell the milk and it smelled off. So, I tasted it ... and it tasted sour. Not soapy, but sour.
Have I lost my entire milk store if she refuses to drink it? Is it safe to even try to get her to drink it? Is there anything I can do to prevent this from happening going forward?
Thanks so much!
