DD is to have a 24-hr test at GOSH to see if she has silent reflux. It involves passing a NGT connected to some kind of electronic monitoring device. She has it fitted, then goes home and eats and drinks normally for the 24 hrs: she then returns to GOSH for the tube to be removed (if she hasn't already ripped it out herself). I can't remember what the technical name for the test is. Has anyone's LO had this and did they find the tube-fitting traumatic (she will need an X-ray as well).
