Lactation Cookies don't really work
Although there are some delicious lactation cookie recipes out there, there isn't enough research that shows evidence that galactogues are effective at increasing milk supply. If you're struggling with the amount that you are producing, I would suggest
You try to increase the frequency of feedings [highest milk production in the very early morning, think 3 AM]
Switch around the positions when you're nursing
Check your flange sizes to ensure they are fitting correctly [pumping]
Some people may see a difference in their supply which is awesome, but please don't rely on them because their are other avenues you can take to try to see whatsup. Also be weary of using herbs [Fenugreek] and other herbs because there are contradictions to every herb and chronic use isn't always recommended.
