Hello & welcome to Just Answer! If you have any questions after reading my answer, be sure to let me know.
I am sorry to hear about your daughter's problems
I believe that a trial of omeprazole / lansaprazole may be useful in this situation in addition of what you are already doing
As regards XXXXX XXXXX on probiotics
these can certainly be tried in cases of allergies/ reflux.
However, there are limited studies in infants regarding the efficacy and long term safety of these products.
So while you may try probiotics, preferably in consultation with your pediatrician
You may not get very startling results, at least with short term use,

thank you for your helpful response. She goes back to the GI in about a week and I will ask about Omeprazole. Her pediatrician and I have discussed Prevacid in the past, however,he was concerned about the side effects it may have on an infants heart. Do you know of the dangers of using it?
