Hey there, my ds has always been difficult to burp, was bf at first and now ff (in the process of trying to get back to bf agian but thats another story). Anyway, we give him infacol before every feed but it still takes ages to get him to burp! we burp him half way through the bottle and then at the end but it takes at about half an hour to get his final burp out and if we give up and assume he has no burps then 9 times out of 10 he'll throw up a while later. we try rubbing his chest, rubbing and patting his back, over the shoulder, sitting up, leaning back, just holds on to it for ages! Any advice???
