Some background info... DS born 7.15 at birth, 8.1 at 2 week, 11.11 at 2 month and 11.12 at 4 month. He is exclusively breastfed and I was pumping some morning to build up a small supply. I would pump one breast, get about 2-3 oz. I wasn't concerned about building a huge supply because I'm still looking for a job.
At the 2 month appt, DS spit up and had a green diaper. Doc asked how often he spit up and I told her about twice an hour after every feeding. I wasn't terribly concerned because it never pair with crying or distress. She suggested that instead of feeding 16 minutes on each side, I tried 14 minutes on each side. Then she asked how often I fed. At the time, it was about every 2.5-3 hours per request of DS. I never really set a schedule. She said my milk wasn't coming in and I should only be feeding every 3-4 hours. I never really attempted that because DS would be crying. I did cut him off after 14 minutes each side and the spitting up stopped.
About a month later, DS was really fussing and pulling away from my right side after about 8 minutes. I thought he was just becoming a more efficient nurser. The left side he would stay longer. The whole month of November, he was pretty fussy.
Fast forward to his 4 month appointment and he's gained only an ounce. I would refer to forums and so much advice is "it's in your head, don't worry about it." Now I know he's not getting enough. I've started pumping after two nursing sessions during the day to boost my supply. I feed him 2 ounces of formula after morning feeding and expressed BM after two other feedings per request of an different pedi. Throughout this whole period, he produces 8-10 wet and 4-6 dirty diapers a day.
Problem: He's growing more unhappy at the breast and I'm afraid my right side is drying up. I just don't hear the let down like I do the left side. How can I get my supply up? I drink plenty of water, eat oatmeal and drink Mother's Milk. Any suggestions?? I don't want to give up but he's so happy after the bottle!
