What age range is the SinuRinse Startkit – (isotonic) – suitable for?

We feel age 4 and up is safe. When a child can take shower without any issues or can swim comfortably, child is ready for the nasal irrigation with some help. Please look at our NasaDrops saline ampoules or vials currently available at CVS, website and few other chains. I feel that Nasadrops ampoule tip that I have designed is perfect for small childre. Please make sure to follow the directions of use.
