My baby is 11 weeks old. Up until the last few weeks she had fed well and hadn't really suffered from colic. About a month ago she did start to arch her back when feeding and the doc said she had reflux and she is on meds. But she still refuses her bottle, sometimes during the day but always in the evening before bed. She screams and wriggles when I give her the bottle and does the same when I don't. She is obviously hungry when I begin feeding. Sometimes I can only get 50ml inside her. Any ideas why she is doing this and what I can try? Thanks
