yeah, well, there's reflux and then there's reflux.
Amen to that! My 3rd DS was a mothers worst nightmare. He could not sleep, he lost weight and was labeled "Failure to thrive" he was hospitalized where he had Drs baffled, I had CYPFS (NZ version of DOCs) visit me in the hospital all but accusing me of Munchhausen Syndrome!! I lived on Brown rice and plain chicken breasts for weeks and still nothing helped.
Every time I was given a new medication to try I felt sick giving it to my tiny baby but knew I had no option.
He eventually stopped even trying to feed breast or bottle and would scream his poor little lungs out when he had to be restrained and force fed with a syringe. He was born a very healthy 4.2kg and at 18weeks weighed in at 4kg

By some miracle a US Reflux Specialist was in the country at the time, he was told about us, and flew to see us.
He immediately requested DS have a upper endoscopy where it was discovered his Lower Esophageal Sphincter was basically broken so it didnt close off to stop the acids coming back up. As a consequence his esophagus was badly burnt and he needed emergency surgery to cut out the affected area, as it was not going to heal and to try and fix his esophageal sphincter.

The difference it made to my baby was unbelievable, we did have some ongoing issues, like starting solids and some respiratory stuff but to look at him now at 9 you would never guess that he (or me for that matter ) might not be here had it not been for that wonderful man, Mr Jamison.

It does depend on the level they have as in hindsight I do believe my 2nd DS had it too but I just thought he was a bit demanding so he wasnt medicated.
