After a feed
Try pumping for about 5 minutes or hand express a little before feeding if possible to prevent too fast letdown. Pump again after feeding and store. Look up how to store properly to maximize nutrition. I personally combined all my cooled milk from the same 24 hours and then bagged it and froze. Water water water. Oatmeal in the morning, prenatals help as well. If needing to increase supply, power pump first thing in the morning, and don't miss your middle of the night pump, even if feeding baby. I have 2 babies that I breastfed/pumped into bottles. And lastly, latch baby whenever possible because breastmilk is made on supply and demand.
I’ve been told by lactation consultant and midwife that pumping is too early since he is only 9 days old and to wait 2-4 weeks. Is that true?
Pump whenever you get the chance so you have extra on the side :)
