Dittos on getting the tube early. My PALS got her tube in Mid-February. We are glad she did. Took about a week to overcome discomfort, etc.
Have not used it for medicine or feeding (yet) but it's great for hydration.
Lessons learned:
stock up on T-pads,
use limited amounts of water on first few flushes, (too much may bloat PALS). After using too much on first flush we now used 30ML.
Q-tips and water to clean around entry to stomach.
if PALS is sensitive to adhesives, elastic , etc, use 100% cotton wraps (T-shirts cut into three inch wide wraps and tied to size works for us),
ask Clinic to shorten the external tube if, as with our doctor, they left more external tube than needed
