Hi,
I feel for you and hope this helps. My daughter has been on prevacid since she's about 1 month old. I know it hurts to always give them medication, but she became a new baby when we gave her the meds. Prevacid works but if the dr prescribes it, be careful if the pharmacy prepares it...I have it prepared for max 5 days. I had a bad experience in the beginning which actually did the contrary effect, it created more acid as the medication became unstable and therefore was not working anymore. this is my own experience and has worked for us. I find that as she is teething, it's getting a bit worse but I'm still at a very small dose of 1.5ml in the morning and 1.5ml at night
If you need more info, don't hesitate to ask
