My 3 year old was very colicky as a baby, I was told reflux and she was prescribed medication but did not help, turned out she had a cows milk allergy and was put on prescribed milk at 12 weeks, was a different baby overnight! It may be more than reflux, my daughter had a blotchy rash mainly on face, runny poo?s after all feeds but this was put down to her being breastfed, screamed at night, took ages to settle her, If you?re bottlefeeding I?ve read Aptamil comfort milk is meant to be good for reflux babies, good luck, hope you have a happier baby soon!
