How do you clean your children's noses so they don't cry? We use a nasal aspirator (with a tube through which we suck out mucus), we drip saline solution with a pipette into the nose and then suction one nostril with the aspirator, all the mucus is removed. It cries, doesn't like it. Are there any tricks/subtleties?
