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.
