None of my kids had reflux, but there were definitely differences in how "urpy" each one was -- since your daughter does have reflux, she will spit up more often.
There are some useful suggestions in this article and from the Mayo Clinic. I'd personally suggest that upright positioning during and after feedings and less milk per nursing session may be useful steps to try. My "spit uppy" child tended to keep feedings down better when I had him tied to me in a sling. So, changes like these may help reduce how much milk she's losing when she spits up.
Unfortunately, since she does have reflux, you may reach a limit of how much spit up you can prevent.
