@Bella Dea,
Home recipe:
- 1 pint purified water (I get jugs of the stuff at the grocery store)
- 1 teaspoon kosher salt (no iodine)
- A dash of baking soda (not much, maybe 1/8 of a teaspoon)
Heat up the purified water until it's a bit below body temperature, mix in salt and baking soda until dissolved. Administer with a bulb syringe -- aim at the back of your head. (If you have one for Ade already, best to get a new one for yourself.)
There are also "neti pots" which can be used for this -- or you can buy a little thing of Ocean or whatever commercial brand, and then just refill with your own saline (as long as you keep the container very clean).
My house is really open, which helps with humidifying I think. I keep the humidifier in the living room which is sort of the center of the house and it goes pretty much everywhere from there. Sometimes I'll put it in one of the bedrooms for a while if it seems more dry than the house in general.
