Hi J.-
Sorry to hear of the trouble with your little one! Call your medical supply company...They make these little clear 'stickers'...circle shaped...with a clear sticky 'flap' that you can run the canula tubing thru. I cannot remember what it is called, but my description will help...I hope. The adhesive did not seem to bother my daughters cheeks. They stay on longer...and they used to also have a gentle adhesive remover as well...or a good 'soak' in the bath...
If he needs a pediatric mask...they make really cute ones with dinasaurs (sp?) and things...could ask about that too.
This is years ago for me...BUT I remember...
Best Luck!
