Girls, my daughter has a constant runny nose, they're somewhere in the nasopharynx. I tried to clear it with a suction bulb, but such a cry is standing, it doesn't work out to remove everything. Laura had them, they said until two years old we don't have the right to suck them out, she advised to irritate the nose so that the baby would cough and the mucus would come out ??‍♀️ Maybe there are other ways? It's very sad for her, I don't know how to help, I thought doctors would help, but there's none here too
