Help with increasing milk supply

Kristin

I strictly pump breast milk due to issues with latching and now I just prefer to do that. I currently pump 4 oz every 3-4 hours unless I’m out and about then it’s a longer period but I’ll pump like 6-7 ounces. My baby boy is currently eating 4 oz sometimes within 2 hours. I have usually a couple bottles in the fridge but I’m afraid I am going to run out or that my supply is slowing down. I have tried lactation cookies but I don’t eat everyday so maybe that’s why. Anyone have any advice?
