and true milk protein allergy. it can (and has with my granddaughter) paralized her colon. to a point of malnutrition.
however, it can be caught with a simple blood test. not the colonoscopy we were told to go thru with her. (argh)
many food allergies will do this and present in odd ways, such as asthma, in her case cystic fibrosis symptoms, intense pain (which she had).....
mary, we heard all the same. apple juice,,miralax, and we ended up with 2 Tablespoons of mineral oil a day (12 lb baby) and she still could not go. it backed up and enlarged her colon badly. and yet, not one ped paid any attention, not to mention the pain she was in. did you hear "she will go when she needs to?" not!
dont quit looking. :) good luck.
