I have been having problems since the day I started bf. At first my lo was latching on great and all that but my nipples were so sore and crack and bleeding that I just started pumping as soon as I got home from the hospital. And I did that for 2 weeks and discovered nipple shields and started using them. By that time he was used to the bottle and didn't like me anymore. So when I started pumping I would get maybe an oz per breast and I was pumping every 3 hours because that is what the doctor told me to do. And I was also instructed to give him formula because he was staying hungry all the time. I didn't know that was hurting my supply more than anything. So I have tried pumping every hour while at home and nursing him at night and in the morning and I get about 12-15 oz per day at work (8-5). But he is eating way more than that. he is now 4.5 months old. Is my supply low or or about right. I hate giving him the formula and I feel like a failure when I have too. I have tried all the herbs and even the reglan but nothing helps. I have increased my pumping to every hour but I can't do that at work so it is every 4 hours. Just need some advice.
