My DS is 4 weeks old. I have been pumping to feed him in bottle as he is having difficulty latching on my inverted nipple. I had tried breast shield the first week and my baby gets frustrated after a minute of sucking. I have been trying every feed and he just cries in frustration where I ended up feeding him in bottle. I was using mipump at the beginning pumping three times a day and my milk supply dipped. I bought the ameda purely yours now and it has been two days sincw i start pumping seven times a day but the milk content i get at a session is about 1.5oz together from both breasts. Am also taking fenugreek. I wanted to know how long before i get an increase in milk supply. I am also doing formula to supplement my baby but would like to stop it. Please help me as it is becoming frustrating to get little amount.
