Pumping question!

Nancy

So I have been feeding my 1 month old son both formula and breast milk since birth. But I actually don’t put him to my breast since he never learned to latch on and now gets frustrated and will not eat if I try. So I pump and bottle feed it to him, but I don’t pump enough. At each pumping session I get out at least 3oz total. What Can I do to boost up my supply? I have tried fenugreek vitamins, water, flaxseeds, Lactation cookies and so forth but nothing seems to work. I did get him used to the bottle only because I will return to school and work soon. I would like to pump and store my milk so that his baby sitter can feed him my milk but I need to boost it up!!!
