I posted this in the Breastfeeding community as well, but I figured I'd post her as well, since this community tends to get more visitors.
I pump twice a day at work, and usually get around 14-15 oz out of those two sessions, so I bring 2 8 oz storage bottles with me and that's always been enough. But my breasts are apparently on overdrive today, and I just got 14 oz (!!) out of just the first session. I'm really excited that I got that amount (is it weird to say I'm proud of my boobs? lol) but I don't have enough room in the bottles now for my second session, since I usually get at least 5 oz out of that pumping session. Is it ok if I store the extra milk TEMPORARILY (about 3-4 hours) in a water bottle? Or can the BPA in the bottle leak into the milk that fast? I hate to waste a pumping session, since I'm trying to build back up my freezer supply, but I of course don't want to make any of the milk unhealthy.
