Hi, guess it is pretty normal due to the teething discomfort. U can try to get teething gel and then put it abt 10 mins or so before u bottle feed so that it numbs the pain and baby is more likely willing to work on the bottle for a longer period of time. Depends on u, u can also consider giving solids if u worry intake not enough. Feed more often at lesser volumes so as not to waste the bm too. Also give baby teether to comfort baby's gums ya
