When I went to my GI, I didn’t have so much a list of questions, but a list of detailed things that had been going on with my daughter that led me to believe that she was still having problems with her reflux despite the medication she was on (forgive me, I am not sure if you LO is on meds or not). I actually counted all the times I heard the silent reflux during the day, as well as video taped one of her naps (that is the only time my daughter really struggled with the reflux was duriing sleep). GOod luck and let us know how the appointment goes.
