Valleychicks, I know that is hard on everyone! Wishing for the best. Two of my four children had what they called Incompetent esophagus. The valve in their throat that opens and closes according to whether or not they are breathing or eating just stayed open. So, everything that went into their stomach would just flow back out. It wasn't a forceful throw-up, just gushing formula when they smiled or laughed or whatever. Have them check that.
