Being at your wits end….. yes, very familiar feeling! I think that all GERD moms surely must feel that way at some point if not all the time. 🙁 I’m sorry your little girl is struggling so much. (((HUGS))) to you.
I understand what you’re saying on how you can’t just try any kind of meds or OTC stuff but who is it that has to approve of what you give your children? The doctor or social services? Sorry I’m so ignorant.
But anyway, something you might want to check into and ask ?? if it’s ok to give, would be a supplement of probiotics and/or digestive enzymes. These have helped my children a lot with their digestive problems. They aren’t a cure all but they have made a big difference.
Here is a link to something I wrote up about why and how they can possible help. https://www.infantreflux.org/forum/forum_posts.asp?TID=16038
I hope that you SOON find something to help your little girl!
