DS is 11 weeks. He is ff although symptoms used to happen when bf too. He fights the bottle, is unsettled and unhappy after feeds. We have tried indicolite, gaviscon, not worked. We have been on ranitidine now for over a week. He seems to be getting worse. He sleeps better at night now but is crying, bottle fighting and upset for large periods of the day now. When napping he will drift off and then wake up 5 mins later crying again. Could ranitidine make things worse? Or does he need higher dose? I just want him to be out of pain! He does vomit but not overly excessively and is gaining weight.
