Hi Becca and welcome! I do wish you luck tomorrow!!!
We do lots of supplements too. I think they're all listed in my signature. Also have made drastic dietary changes. It's really been worth it.
It's interesting your reflexologist mentioned she thinks your daughter gets headaches at night. My son used to get terrible headaches at night. I think he was in second grade when they were the worst, but he had them in first grade, too. We had his eyes checked, went to the doctor, etc., etc., and nothing showed up. No lower back pain, though....
As for seeing a holistic doc, we haven't yet, but we may in the future. We have used a chiropractor for many, many years. He reminds me constantly of the importance of digestive enzymes for Crohn's. He calls them "proteolytic enzymes" though, and wants to sell me the brand he carries. Right now we're simply using Ultra-Zyme by Nature's Plus. I've used them for 15 years or so for myself.
You may have already looked into this, but probiotic strains for little ones are supposedly slightly different than those for adults. I just don't know what that age cut-off is and can't remember the difference in strains. Something to look into in all your spare time
I will be thinking of your little one tomorrow!
Do let us know how it goes!
