I exclusively pumped for my first baby. It wasn’t my plan but it’s just how it ended up. I want to exclusive pump for my 2nd which is due early February. With my first, my milk didn’t come in for 4 days or so. I would like to collect colostrum before birth (if approved by doc). Does anyone have any advice? When should I start? How much should I save in each milliliter dropper? How many? How long should a baby have colostrum? I freeze it right? Do I bring to hospital? Thanks!!
