Yet another specialist??

18 months after the feeding tube came out, we're still looking for answers as to why it ever had to go in.  Auggie still struggles with food and often gags on his own saliva.  Our doctor has recommended seeing an endocrinologist next.  He is still not on the CDC growth curve for weight and is about 15th percentile for height, a drop since we last had him measured.  Could we be looking at a hormonal imblance or a thyroid problem?  My gut tells me, no....Adding another doctor to our list means more bloodwork and other work-ups.  I'm on the fence. Update: His wrist x-ray showed his bone age to be at 3 years of age when it should have been 3 and 7 months. The doctor determined that he was not lagging enough behind in growth to necessitate seeing an endocrinologist.  Usually a lag of 12 months warrants seeing an endo doctor.
