My son (3 months) was the same way. It gets better I promise! For us it was any strong gas relief medicine, finding out the cause of the reflux (also turned out he lacks proteins that break down lactose and soy; so check for that too!), feeding him while he’s in a sitting-type position between my legs and keeping him there for 20min after he’s finished (at night only but that’s when it’s the worst), and burping him every 5 minutes during feeds. It’s a lot but it worked so well! Good luck mama! ❤️
