How old is she?
Really recommend the book/audio book “Why infant reflux matters” as it massively helped me figure out what was causing my little ones reflux and pretty much stop it completely
The only thing that solved my baby's reflux (it was really bad) was Famotidine. Please talk to your pediatrician to see if it's a good fit.
I am so sorry sorry, that's so distressing. I wish I knew anything about it - all I can suggest is going to your pediatrician. Sending thoughts and prayers ❤️ you got this mamma. You and your sweet girl are gonna be ok!
