My son was born at 37 weeks and 2 days. So he according to the lactation consultant he is a late term preemie and lazy because if I was still pregnant he would still be growing and getting ready. So besides pumping what can I do to safely increase my milk supply? The pediatrician we saw the other day made me feel like I am horrible at this but I really want to try this! Pumping and massaging has helped decrease the pain and some swollenness. So I just want to increase my supply

Thank you for any advice
