My 9.5 week old has been EBF with the exception of a few bottles of pumped milk here and there so I could leave her with someone. At most she gets one a day, 4 oz. She usually just nurses from one breast per feeding for about 15 mins every 2.5-3 hours. The last few days I can't get her to finish a breast! She will eat for maybe 5 mins then start screaming. I burp her, put her back on and she screams again. I know I have a good supply and good let down, but surely she isn't finishing that fast?! Any advice?
