Reflux help!

Sheila

My 2 month old is experiencing bad reflux. To be honest, our pediatrician has been useless other then the usual tips like sitting her upright after feeding. Last night it was so bad she started choking and turned beet red. Couldn’t breathe for a few seconds. She is formula fed. Is there a special formula for reflux? Special bottle? I’m willing to do anything to help her!
