Just wanted to agree with you — infant GERD does seem to be much more common than most people realize. I know several babies who are/were called “colicky” (just like some doctors labeled my boys), when most likely they were suffering from reflux and/or protein intolerances.
Also, while I think infant GERD diagnoses are on the rise, I definitely know that babies have been suffering from it for a long time, probably since the beginning of time! My poor mother just about went insane with my younger brother 20 years ago — he projectile vomited all the time, cried inconsolably, and never slept. She never got a diagnosis and just suffered through it, but now she tells me that it had to be GERD and/or MSPI, after helping me SO much with my two refluxers right after they were born. It really makes me thankful for this forum (and Prevacid!) and just the fact that we can get relief these days for our lo’s.
