Mine came on day 6/7. The volume increases on day 9/10. You can try pumping in between direct latching to encourage more milk production. Remember to drink 3-4L of water also Can feed formula in the meantime. Hang in there, the milk will come!
My flow started coming in at day 5/6. I’m at 2nd week now doing 3 hrly pumping with 120mls accumulated. You may have want to have a post natal massage so that can help with the flow and unblocking the ducts
Mine came at day 5 also, with only 10-20ml for afew days. now my LO is 20 days old, I’m slowly increasing supply.. still at 120ml for both sides at best
