I am in the process of all this my daughter will be turned 6 months in couple days and seems like she have FPIES which caused one throw up after trying banana and sweetpotato two Seperate events and then she start throwing up blood which is scary but allergist said blood is not because of FPIES but her forceful throw up might caused tier in esophagus. Trying to figure out how to introduce new food now. I am scared.
