My 18 month old, Charlie, has been in feeding therapy for almost a year due to her sensitive gag reflex. Her doctor has diagnosed her with a feeding disorder. She also has terrible reflux and is on zantac for it. I have discovered that she spits up less if she eats partially hydrolyzed whey protein formulas as opposed to regular milk products. (Yes, she is still formula dependent.) Every baby is different. These are just a few ideas that happened to work for us. Good luck to you.
Yes, keep us updated. I'm interested in learning more ideas.
