I've been giving LO a bottle of pumped breast milk here and there. I had a measly 17oz and defrosted my last 2oz today. Just went to make a bottle and most of the bag had leaked into the container I was defrosting the bag in. It wasn't an issue of the bag not sealing tight bc when I lifted the bag the leak was clearly from the bottom.
There was no leak when I filled the bag so I'm not sure what happened. The only thing I can think of is this bag was from an opened box leftover from my pumping days with dd1 over a year ago. But I don't think plastic will "weaken" that fast?

I'm afraid now! Anyone else ever had this happened?
