Dude, we have used the neti pot here too (well everyone except myself as I do not have allergies), and amazingly the kids kind of enjoy it! But we stopped using it because I couldn't get it to go in through the nasal passage since they are so congested. Have you experienced this?
I need to go back to this. I think it definitely helps so long as the nose isn't too blocked, especially with the mucous buildup in the throat.
