My son is 3 months old and I have breast fed him since he was born. But for the past two weeks we have had to supliment formula while Im at work because i would have no let down when I would pump even when my breast were so full it almost hurt. It was going great nursing at home and him being bottle fed at while i was gone and I only work 5 hour shifts so its only 1 bottle that is suplimented. Lately though he still acts hungry even after eating on both breast where as he usually is a one side feeder. Could my milk be drying up even though he is still nursing?
