Hi, was wondering if anyone could offer any explanations other than reflux to my DS2 regular spitting up of his feed. He is 3 1/2 months and for the first 3 months was regularly feeding well and putting on 8oz a week. Since he turned 3 months he has suddenly started spitting up substantial amounts of his feed. He doesn't do it one go, or directly after he has been fed. It can gradually all come up over the space of 2 hours. As a result his weight gain has dropped off substantially (although he is still gaining - 2 oz per week). I have been reading about infant reflux and I am not sure whether this is what he has as he doesn't have the bad breath, obvious discomfort after feeding etc. In fact he seems fairly content. I have tried keeping him upright (doesn't work), keeping him at an angle (doesn't work that well), keeping him still (works, until I move him - be this 2 mins or 2 hours after the feed, then - spit up). I thought that infant reflux was supposed to get better at 3-4 months, not suddenly start. Any ideas? He is exclusively BF, but does have his final feed from a bottle (expressed). Thanks
