My baby was diagnosed with Gerd starting at 14 days old. After having him home for only 3 days from the NICU, I kept calling saying that he NEVER slept and always screamed. Not morning, not afternoon, not night. He would pass out and then wake up 10 minutes later SCREAMING. They changed his formula 4 times. They put him on Zantac (yes it does need to be given consistently or it wont work). After 1 month of changing his formula, zantac doses, feeding schedules, reflux beds, burps, no burps, etc they referred us to a GI. Since then he has been on prilosec and now nexium, nutramagin, and cereal in his bottle. At 5 1/2 months now he is finally getting better. He still projectile vomits, and still never sleeps throughout the day, but he is finally a happy baby. As I heard alot of opinions of putting my baby on medicine, noone knew the pain I saw in my babys eyes every second of every day.
