my daughter had ten of those twelve, so I understand your pain. In children under two the medicines they use for reflux must be adjust quite frequently because of weight gain--so please up the dosage as suggest by your pediatrician. If you are formula feeding instead of breastfeeding, PLEASE switch to a read-to-feed or concentrated formula if you aren't using one already. To be honest...after all our troubles, when we switched to the concentrated formula at 6 months old, she was like a different baby---cut the spit up in HALF. Also, if you can use the enfamil gentlease or the carnation good start formula, you would be in a better situation--it really is easier on their tiny tummies.
Keep your baby upright for at least 20 minutes after every meal.
Ask your pediatrician about reglan if you aren't using it already--it is a motility drug--meaning that it speeds up the rate at which food moves from the stomach into the small intestine---less food in the tummy means less spitting up and therefore less heartburn for baby.
If you've tried all of those, you might ask about thickening formula/breastmilk with rice or oatmeal cereal since your baby is older now...we had my daughter eating 5oz bottle with 5tsp of rice ceareal in them at about that age---and my daughter NEVER took more than 6oz in a bottle at any age, and NEVER had more than 28oz a day of formula---which is on the low end for any baby.
