my DS is older than yours but we went through what you've described and he is still suffering problems now. I BF rather than bottles, but found that whilst we couldn't always stop him being sick, we could reduce the frequence by stopping each feed 3-4 times to wind, then continue the feed, then wind, then continue the feed etc etc. When he started eating solids, (which we did early at 16 weeks on the advice of HV's) he was still sick with the purees, and they came up with such force they would come through his nose, which really hurt him, he would scream so much and sob uncontrollably. We stopped and restarted at 23 weeks and i think we should have waited a few more weeks. So from my experience with a reflux baby, i would delay weaning as much as possible as it was distressing for DS and for me. When we moved onto the more textured foods about 7 1/2-8 months, things finally started to improve. He is keeping them down better but still sick 1-2 times a week. He has had trouble with eating, he gags easily and can empty his stomach very easily and so we had to take it very slowly. He was losing weight at one point due to his being sick. He is now 9 1/2 months old and we are finally getting somewhere. He can now eat a weetabix and 50g fruit puree at 6am, BF at 8am, textured dinner and petit filous at 12, BF by 2, textured tea and 50g puree at 4.30 and petit filous at 6 for supper, BF at 7 and sleeps from 7.30-6am. His meals are all cheese or protein based with potatoes or pasta in them. Our success was to feed little and often and not to rush things. He is only just starting to manage finger food snacks, can now eat a rice cake, managed a small amount of cheese spread on toast the other day, and can cope with organix puffs. He is still sick, but we are starting to win the battle, and he is starting to enjoy eating and becoming less scared of the high chair, but i still can't relax and give him lumpy food like other babies the same age as him can cope with. Despite being slow at progressing with eating, by doing it our way, he has now put on weight, and when weighed last week was up to 22lb 2oz! Please enjoy your time with him as a milk guzzling baby, don't rush into weaning until he is older.
