Lactation cookies?!

Haily

I am a first time mom. I planned on Breastfeeding my LO but with his tongue tie, he woulent latch at the beginning. So i pumped. Well that still ended up not being enough for him. I wouldnt produce enough within the few hours beforw he got hungry to feed him again so i started supplementing. Now i can only pump enough once a day to make him happy. Ive tried pumping every 3 hrs on the dot. Ive tried some lactation bars. I couldn't stomach them. Ive seen a few recipes where people use like betty crocker cookie mix and add the brewers yeast, flax meal, and oats. Has anyone tried this and been successful with upping tyour supply. I go back to work in 5 days.i have asmall freezer stash already but i want more. I dont wanna rely on formula.
