Can anyone recommend a good paed in Melb for infant reflux?

Poor Mia has been suffering for a while now, and the Zantac she's on seems to be making stuff all difference. My GP reluctantly gave me a referral to a local paed but when I called them, I can't get in until 22 October!!

I can't put my girl through this for another 6 weeks before we even see anyone - she's in pain every time she feeds and it breaks my heart and often leads me to cry along with her. She also wont take a bottle, so if she's having a tough feeding time, it means she usually goes without as she won't take it from me or a bottle

Can anyone help?
