Because the tube does not go into the nose, your baby will not get hurt if she moves. Also, you cannot suck too hard.
Only use Nosefrida® for cleaning babies and children's noses. Do not use in ears or throat. Do not blow air into the red mouthpiece while tube is placed at your child's nostril. Nosefrida® is not a toy! Keep all parts out of reach for all children. Never attach Nosefrida® to any kind of mechanical aspirator or machines.
