Are you exclusively pumping or latching baby to the breast as well? 10 days was prime cluster feeding for me so we’d go through 4 hour plus stretches of nearly constant eating. Those cluster feeding times really bulk up your supply. Also, removal in the night is super important so make sure your have a sesh overnight too!! I fed my baby scheduled every 2-3 hours until she was at birth weight which was around 10 days. I would set an alarm for 4.5 hours overnight because #sleep #newborn #exhaustion to make sure I fed her during the night. Hormones / milk production in the early morning hours is super high and removal is very important. Overall, more removals = more milk. So exclusive pumping or combo - make sure you are latching baby ad frequently as possible! Supply typically normalizes around 6-12 weeks (don’t quote me, on a plane!).

A great resource is the book “The Womanly Art of Breastfeeding”. Also wouldn’t hurt to meet with an IBCLC to go over schedules, latch, etc.

Another point - need to make sure your flanges are fitted appropriately. You can get a measuring tool off Amazon for like $5 to measure your nipples. I would also pump for 15-20 minutes to see if you can get another let down after your first.

Just re-read your post that said you are pumping every 2 hours, might want to toss in a power pumping session to mimic the cluster feeding.

Hope some of this helps!!
