Both of my girls had full-on reflux. They would always spit, and sometimes actually vomit an entire meal, which was frustrating when the meal took 45 minutes to get in there!! The one things that really seemed to make a difference for them was to make sure that they stayed upright for at least 20 minutes after every feeding. I could not have survived the early months without a sling, for that reason alone. Burping helped too, although even with a burp there was often a good bit of spitting.

Again, good luck. Hope some of this helps!
