I wouldn't worry about it. She's gaining beautifully, her lungs are clear and she helping keep mom from getting too uncomfortable. Eventually mom's teats will adjust to the lesser demand and she will produce less milk. They will grow up the size they are meant to be. I had one that was 14 oz. at 10 days and she's 5.5 lbs. as an adult. I'm so glad she's thriving.
