The idea is yes, you give bigger bottles so they eat more at each feed to keep the same volume overall!
That said, with a refluxer it can be a bit harder. How is her reflux being treated? Smaller feeds more often are better for refluxers because of what you have found - more in their tummy means more to come back up (been there, done that twice

)! Smaller more frequent feeds often work better.
Is she draining those 6oz bottles? If she is you should really add another oz in anyway so as she is a bit bigger now and should have a bit more tummy capacity you could try bigger bottles again and she may cope better now. The fact she just about makes it to 3 hours shows she could do with a bit more at each feed now, or it could be the reflux isn't controlled and she is lloking for food to soothe her throat.
