I just found a medela bottle in the fridge with 2.5 oz of breastmilk in the back of the fridge. I'm pretty sure it was from last week, around Christmas Eve, and that it got pushed to the back by all of our leftovers. That may not sound like a big deal, but it's about two pumping sessions for me, so I'm very sad. It was very separated - it looked like water with white paste on top - and there's no way I was going to risk it, even though it didn't smell spoiled. Ugh! I'm so mad about this.
