Blessedatlast, I haven't tried the herbal supplements yet, but it's on the 'to do' list. Maybe you should try the cookies again? You sound like you're in a feeding and pumping routine, and if you know you normally pump 300ml a day, you will know from the volume you pump if the cookies are helping. On the other hand, if you can pump 300ml a day AND your son is still fully BF, maybe you don't need to increase your supply any more! In my case, I know DS is getting about 370 ml and I'm pumping only about 80ml in 24 hours.
