Oh your poor little man . I can't give you any Losec advice, but I wanted to suggest trying a paediatric chiropractor. My DS2 had reflux and I took him to our chiro before putting him on meds and after one adjustment his reflux disappeared within 5 days. Sometimes when something is out it can cause other problems like reflux, colic, wind, etc. to occur.

I hope you find some relief for your bub soon .
