Milk for my preemie

With my son I hardly ever got an ounce out of each breast at time. I just had an emergency csection on Wednesday due to preeclampsia and my daughter is in the nicu. She isn’t eating yet as she is still learning how to breathe but I have been pumping like crazy to try to build up a stock pile for her for whenever she is ready. My milk came in day 2 and it’s day 4 and I just pumped this in 20 minutes!🙌🏼🙌🏼🙌🏼 I’m just so proud of myself. I feel so helpless in this situation but this is the one thing I can do for her so I really want to do the best I can!
