Reflux?

Kadey
I read online about reflux and I think my baby has a lot of the symptoms...the last few days she sometimes has trouble eating all her bottle, gets the hiccups, is more fussy then usual, and had been spitting up more. I have a appointment in a couple days for her but I was wondering if there was any ideas of what I can do to help her till then. When I feed her I stop and burp more often and make sure she is in a sitting up positions and also make sure she sits up 20-30 min after feeds but still dosent seem to be helping her.
