I am attending cosmetology classes, thus forced to pump during my 13 hour days of school. I do this 3 consecutive days a week. when my son was in nicu, born at 28 wks ges, i used a hosptal grade pump and produced more than nesscery for him, so I stored the rest. When I returned to school, my husband used this milk to feed our son, but the frezzer is now empty. What I pump at school is not enough to keep our little one satisfied, so my husband has to give him formula in the afternoon. At school, I drink plenty of water, snack all day long, and started pumping every 2hrs instead of 3, but still only get 1-1 1/2ounces a pumping session. On off days, I nurse whenever he wants. It takes about a day to produced what he needs. I need suggestions on how to make enough milk during those long school days, please. Oh and I only need 2 more weeks to graduate, but still worried about my supply.
