I rarely burp either BipolarGirl and wish I could. My oldest daughter is just like me and we only do it once in a while. My youngest can burp very easily ....even on command lol. I think Didgee Eeyou may be on the right track because me / oldest daughter have reflux esophagitis ...so I'm thinking its because the opening at the bottom is too relaxed and not enough pressure to release a burp. This isn't fact and just my speculation.
