I used Garcol (spelling) its a natural thickner added to food of stroke victems.
My pead is natural medication friendly! bub hadnt gainded weight or slept much due to pain and progectile vomit, i was warned he didnt think it would work, but tryed it as we where in hospital, also she slept with a 45 deg angle, after 9 days in hospital, she was discharged (9 weeks old) and finally came of thickened feeds at 2.5 yrs. She did have bad teeth from the constant vomit in her mouth.
