Hi, my poor little DD is just absolutely unable to lie down comfortably on her back. I suspect colic and reflux but not getting anywhere with treatments. She sleeps well in her sling, lying upright on my chest or on her tummy over my lap, but put her on her back and within 20 minutes max she will be writhing and grunting in agony. Left unattended this erupts to colicky howling which can last hours. She is bf on demand every 90 minutes 3 hrs. DH gives a bottle of expressed milk once an evening so I can get 3 to 4 hoursin the spare room. We have tried infacol, colief, infant gaviscon, elevating co sleeper cot with books and several sessions of cranial osteopathy but not had any success. Know I probably just have to wait it out but hoping for some solution. My back is shot from the sling and I am sooo tired...
