Hi Cindy, Sorry for the late reply. I was on vacation for a few days and missed your message. Thanks so much for the update. I am glad you were able to have a good discussion with the allergist about the head tilting. I know it is frustrating not to have instant answers and solutions. It can take a while to sort out all of the symptoms and determine the root cause. While it might seem like the doctor is just adding more acid reducers to the situation, using medication to diagnose reflux is fairly standard. If a baby responds to the treatment, it gives the doctor an indication that reflux is the cause. It can even avoid the need for testing in some cases. There is some evidence that babies and young children metabolize the PPI medications faster than adults and may need a higher dose. This method of testing via medication certainly takes more time and effort but it often gives important information. I am glad you have a secondary plan to consult with the GI specialist and neurologist. So let me know what the blood test results are and what happens on the higher dose of medication. Hang on for the roller coaster ride to a diagnosis! Lots of ups and downs... I am here for you when you need to chat. Jan The Reflux Mom
