DS is 12 weeks old, EFF. brings up milk or sometimes watery fluid even hours after feeds. Diagnosed with reflux and prescribed gaviscon but doesn't make much difference. He is very windy and always struggling with wind even though he burps well after feeds, and seems to go red and blotchy in the face when feeding. Questioned CMPA but HV said highly unlikely. Could it just be the reflux causing this or could it be an allergy of some sort?
