my son used to have reflux very often when he was younger. these are the advice given to us by pediatrician and other mommies i find quite helpful:
1. try not to carry her or jiggle her about after feed, let her stay put if possible.
2. dont't agitate or over-excite her i.e cry or laugh. let her relax or stay calm after feed
3. must burp after feed, but dont't over-burp, i usually do not more than 10mins.. or after son burps.
