Will was diagnosed at hospital but not with it bad - just a slightly loose esophageal sphincter. After reading everyone's earlier entries i think he must have had it very mildly. Right from the start he was managing to spew through his nose while i was still feeding him so at day 3 he had a barium swallow which didn't show anything so they said we could go home. on the way home in the car he threw up loads of blood so we turned the car round and were re-admitted. He had an endoscopy the next day which showed he'd slightly injured the top bit of the lining of the stomach with throwing up but that it had mostly healed already and had the slack sphincter. For the first 3 months he was so uncomfy after feeding but he didn't scream for long periods. I got very good at dozing with him sleeping upwards on me! We tried zantac but that did nothing so Losec was next and that improved things abit. We met someone who had been through the same thing and all the drugs who recommended plain old fashioned gripe water as well as the losec. The first night we gave him it he slept for 8 hours straight!!!!! The 8 hours wasn't repeated that often but it certainly marked a turning point. We finished the losec at about 5 months and although he still chucks for England he is not uncomfy and will vom mid smile and keep on smiling!Thank god for tiles - our rug is thankfully reversible so once he finishes with it we can turn it over. Not sure about the carpet in the bedrooms!!!
