Does anyone have experience w/ vomiting due to GI problems or aerophagia? I know there are many causes for vomiting: overfeeding, gagging, behavioral, reflux. My son has vomited for all those reasons, and I've gotten good at knowing which thing caused each episode. But, there are times when he'll vomit for no apparent reason. Usually those times immediately follow bottle-feeding and he'll vomit up his entire bottle. I'm fairly certain that on most of those situations, it's not due to overfeeding, gagging, reflux (which he gets Prilosec for), or behavior. I'm wondering if it may be due to a GI problem or possibly aerophagia. He doesn't have severe gas and he does burp well during feeds. But often times during these episodes the vomiting occurs immediately after a "deep" burp... meaning that I can literally hear it coming up through him! He doesn't ever appear to be in any pain. He does have a g-tube, but we don't really use it anymore other than to vent him on occassion. He leaks a lot from the g-tube, could air be getting in? We have an appt with a GI specialist next week, and I want to be prepared and educated! So any experience/thoughts you all may have would be greatly appreciated!
