DS2 has this (he is now 18 months old).
At the begining of the month I decided to stop the medicine to see if he was better and he seemed OK for a couple of weeks.
He has had a relapse of it over the weekend and I feel really awful. GP told me to phone the consultant and get an appointment ASAP (on Monday) as prior to me stopping the medicine no-one knew whether or not he had grown out of it or not.
The Omeperazole he takes was obviously working well.
I wonder if anyone has had any tests for this and how long in their experience it has lasted.
Plus any advice of what to ask on Monday?
