This is my second child, she's almost 5 weeks old. I've been successfully breast feeding since birth. She did have jaundice and had to have photo therapy at the hospital, but otherwise healthy. I've started pumping at home. My first attempt was pump on one side while she's eating on the other. I got 2.5 ounces, yay. The second attempt switched sides and barely got 1 ounce. I manually expressed and got it up to 1.25 ounces. My daughter seemed very upset like she was still hungry, gave her the side I pumped. Still fussy but calmed down. My third attempt I switched sides again and pumped while my daughter was sleeping. Barely got 0.5 ounce. I pumped both sides, repeating the original side and got 1.3 ounces combined. She's now eating. Am I doing something wrong? I don't think my supply should drop so much. The pump I'm using is Ameda. My insurance company provided. I had similar problem with my first daughter and gave up. But I'm going back to work in 3 weeks and want to stick with it this time. I would solely breast feed if I could, please help.
