Girls, hello ? Can you please tell me if your kids also had this and we'll be not alone like that? For a month if not more, we have runny nose, I rinse with Aquavital baby and aspirator, we pull out... We are 7 months old, 5 teeth popped up, thought it was snot on the teeth, but I doubt now... Is it really possible for them to be so long? Transparent snot in color.
