I donated a large grocery sack full of pumped milk to my CNM's practice. I've been pumping for about 2 months and getting around 6-8 oz/session. That's at least 360 fluid ounces or close to 3 gallons/12 liters. I finally have freezer space again!
I pump once a day. I used to pump in the morning, but just switched over to pumping right before bed. Ivy has a long stretch when she first goes down at night, so it keeps me from getting too engorged.
Even though I have a lot going on, I really wanted to donate breastmilk this time. And since I'm not planning on getting pregnant again, I could probably keep pumping & donating for a long time if I wanted to (my milk supply plummets when I'm pregnant).
Here's Ivy on 2 1/2 months of breastmilk. I love her big button eyes.
