If my baby seems to have the symptoms of ger- pain with spit up and/or vomit, arching back, should she take zantac (ranitidine)?

All babies reflux. To get a burp out of a baby you are getting air to reflux from the stomach. All babies also spit up. When the baby seem to have constant irritability & spitting i often try some antacid medicine to see if it helps. Zantac (ranitidine) is one of several that can be used this way.
