burping troubles

Kaitlynn
anyone elses newborn having an issue with their LO seeming to fight burping??? im exclusively breastfeeding and shes otherwise healthy. my pediatrician says its normal/that shes fine. 
my LO seems to 
a. not be able to burp, it kinda eeks out of her throat. makes her fussy and she fights it... 
b. only farts but hates doing so so she screams and cries 
its been a week of this and shes only 2wks... i feel so bad cuz she will occassionally scream in pain before passing gas, and i try to help her burp so that doesnt happen, but like i said she wont... any tips?
