Pumping Mom help

Does anyone have tips on how to increase your milk supply but not a crazy increase im currently pumping about 4 ounces more than what he eats in a full day and would like to increase it a small amount but nothing crazy as he’s not a huge fan of frozen milk. Any tips are welcomed plz. Currently just trying to drink more water and have started to drink one body armor a day. #pumpingtips #pumpingishard #pumpingjourney #increasemilksupply
