IME not all babies with reflux are the same. For my ds there were no issues with weight gain. He would simply vomit around 1 oz every feed and lots in between. He was also very much in pain when lying down flat or when feeding. These last symptons improved when his reflux was diagnosed gaviscon was given and i altered his feeding routine (little and often, changing breast only every couple of feeds etc. ) Anyway around 16 weeks, things started to get much worse. With hindsight I think he was going though another growth spurt but was taking the maximum amount of liquid his body could take (reflux is made worse on a very full stomach). He used to cry and scream at feeds but refuse to come off the breast. Think he was both hungry and in pain. HV advised weaning and given that he could sit up with support and was helping me with his medicine spoon, thought that she was right. So at 17 weeks I started Initially things got worse rather than better mistakes i made were a) offering solids and feeding at same time - too much pressure on stomach and b) not giving gaviscon before the milk feed and waiting still after. DS really started to feed himself around this time. Hand in bowl, hand on mouth etc. Started to give finger food (banana, avocado etc. ). By 26 weeks was on breakfast lunch and tea and feeding himself by eating with his hands. Used to put loads of things on toast. Started to drop breast feeds and by around 7 months was down to 5 a day. Reflux improved and was able to give up meds. by 9 months. hope this is of help
