Hi Christine,
I remember you! I was on the group several years ago when my little boy Jordan had reflux really bad.
I haven’t heard of any of the studies you mentioned, but we are still battling ‘some’ level of reflux around here. My older son, Josh, who is now 12 has been having episodes recently. Instead of using any of the PPI’s I’ve been working with him on watching his diet. He also uses the same old Mylanta he did as a baby (Cherry Supreme) & Pepcid. Seems like processed foods really aggravate his reflux, so I fuss at him to eat more fresh fruits and veggies!
I hope your little girl is doing well now!
