My 11 yo daughter uses the "kidsta" mask for kids,by resmed and the swift mirage for adults in a small size.  We switch between the two because it seems to help with compliance when she doesn't want to ware her mask.  Do all the manufacturers make machines and masks for kids?  Are some better than others?  Where to look?  I've done a web search and it is a bit overwhelming.

Not all manufacturers make masks specifically marketed for kids.  Resmed is the first (and I think currently the only) company to be cleared by FDA for pediatric use).  Doest the mask need to be cleared by the FDA?  No.  Is it nice that it is?  Sure, why not.  I appreciate that Resmed is at least recognizing the pediatric population and the needs therein.  Most companies make adult masks, but in several sizes (petite, xtra small, etc.), which can be assumed to be used for kids.  If the shoe fits, and, ummm doesnt leak, or cause a sore nose and/or forehead, or crying~~ wear it.
