I need help ... I went back to work yesterday and I haven't stored any milk at all I usually just give her my boob on command but since I returned it's hard today I only pumped 2 1/2 and she obviously eats more than that.. idk what to do because I don't want to supplement her I have heard so many bad things about formula that I really don't I already got pills from target called lactation plus... and they seem to help but I'm desperate idk what else to do. .
