I pumped every 2-3 hrs during the day after baby ate and every 3 hrs at night storing the leftover in the fridge
Thawed milk use within 24 hrs don't refreeze, keep in fridge fresh milk 3-5 days but not in door of fridge. Store in deep freeze 8-12 months.
The one thing I learned from donating milk and working with lactation specialists is that breastmilk is all supply and demand, the more skin to skin contact you do and nursing on demand you do the more milk your body will make. No special teas needed :) make a demand, pump Kore nurse more etc. Always stay hydrated, drink a ton of water I'm talking around 1 gallon in a 24 HR period of time make it a goal it helps 1000x trust me. Also if you are feeling down about it you can eat oatmeal that always boosted me when I needed to make a personal ounce quota. Brewers yeast boots milk supply also. You can recipes for lactation cookies and shakes with it in it. A lot of women use it to boost milk supply.
With a drs OK you can look into fenugreek and sweet fennel supplements, some women I worked closely with in the NICU used them when they had medical issues causing their supply to dwindle. :).hope this helps
