My 14 month old daughter is vomiting at least once a day. She never throws up what she eats, only what she drinks. She was diagnosed with acid reflux at 4 days and was on Zantac for about 9 months, she got better so her pediatrician took her off the meds. Then about 12 months, she started throwing up 5-6 times a day. They started the zantac back, no luck, so swapped her to prevacid. This worked for about 6 weeks,now we are throwing up again. She drinks soy milk.
