I am a new mom. My daughter is 4 1/2 months old and I have noticed that milk supply has decreased. I work 6 days a week 8hrs a day and while I am at work I pump every 2-3 hours. Everytime I pump, I am only getting maybe 2-3 oz out of both sides. I feel like I'm not supplying milk fast enough to save for when I take her to daycare. I need some advice on how to increase my milk supply fast.
