saline is good. i would just make sure it doesn’t contain anything other than water & natural salt. what would also help is a nasal aspirator after the spray/drops. also, a humidifier with an oil diffuser. eucalyptus essential oil helps so much with stuffiness. be sure to use distilled water. & you could use a natural balm with a few added drops of eucalyptus & lavender oil as a chest rub. not sure if you have an air purifier, but those things are magical.
Saline spray is usually just salty water. Personally I already had my contact lens solution which is also saline so I used that, but yes that’s okay, it’s saline. Also get a diffuser where you can put baby Euky bear solution in and the eucalyptus/menthol it emits will help your baby breathe, we have it running all night when my baby is sick or can’t breathe
Yup, used these before. Spray it then used the nozzle thing to unclog the nostrils. She didn’t like it- but definitely helped.
