GERD OR REFLUX IN A TODDLER / 22 MONTH OLD.

Anyone’s baby or toddler is dealing with or has dealt with reflux? I am absolutely losing my mind over here & yessss I took him to the Doctor. For the last almost 3 entire weeks, my baby has been puking EVERY SINGLE DAY AND ALSO GAGGING TO REGURGITATE BUT SOMETIMES IT GOES BACK DOWN. I am distraught. Luckily he isn’t losing weight. He currently takes famotidine 2x a day but is there anything else I can do to help or keep it at bay? He’s puking at least 3x a day and it’s stressing me completely out. We went to the doctor and we’ve been referred to a pediatric gastroenterologist but I have to wait on them to call and wait on the appointment which I’m sure won’t be anytime soon. Someone that’s been through this with their child pleaseeee help me. ☹️
