My oldest had horrible reflux. He was miserable. He screamed bloody murder because he felt so bad. He threw up profusely after every feeding. We didn't use spit rags with him. We literally used bath towels because a good portion of everything that went in was definitely coming back up. At about 4months or so, the screaming/colic-like symptoms improved, but the upchucking kept on. We were sent to a pediatric gastoenterologist who told us the vomiting would end once he stood up and started walking. I was like . . . Right. But he was exactly right. Gravity works. He started walking and the issues subsided on their own.
The one lingering effect was that due to all the vomiting, he developed a touchy gag reflex, and getting him off of smooth pureed foods onto any food with texture took forever. The texture made him gag, and gagging of course made him throw up. It took time, but he's 25 now and has been off pureed foods for 23 1/2 years now

Unfortunately, my message to you is that no medicines, treatments, remedies, etc. made the least difference in improving his condition. It was time that made the corrections. I know exactly how exhausting and worrisome this is for you. But physically your baby will be fine given time. My best advice is to take this as much in stride as you can. Rest when you can. Try not too stress too much ( yea, I know . . . ). This really will improve as you adapt to this just being what it is right now. Sorry your baby's feeling badly. We all hate to see our baby's in distress.
