Had a baby boy 3.5 days ago weighing 10lb. He fed like a champ for first 48 hours..latch fine. Uesterday my breasts felt full and sore and he was so sleepy he barely used them. Overnight snd from this morning he is refusing to suck. My supply is crap (has been twice before) and my let down is slow. He is latching on but if no milk there he just stops and refuses to start again. Midwive no help. Am pumping approx 1.5oz every 2.5 hours or so to give him. Any advice on how to get him to suck?
