I tried giving probiotics to both of my kids, a refluxer and non-refluxer. Does your daughter have milk or soy problems? If so, check out the label. Many probiotics have milk and/or soy in them.
The probiotics seemed to make my ds, the refluxer, worse. He is MSPI, but the one I gave him had no milk or soy products in it. The only ingredients were Bifidobacterium infantis and maltodextrin. My ds seemed to not sleep very well when I was giving him probiotics. Maybe from gas?????
I left my dd, non-reflux, on the probiotics as it seemed to help her bm’s. She tends to have runnier bm’s.
