trust me, if the reflux is that bad, you are going to want a specialist in the longer term anyway. It is a great thing he offered the referal. They really do not do much at the beginnig – with infants, they always try the trial and error method before they do any further tests. IMHO< the upper gi is a bit of a waste of time. If the reflux is bad you need a ph probe and endo, but you can talk to your ped GI about it.
Something to consider though, if the wait is going to be as long as you say, is to start your baby on prevacid right now. The ped offered so i would take that offer because things can go downhill pretty quickly with the reflux (I have only read the last few posts so hope i did not miss anything major)
