  "textContent": "There's no nice way to put it: Small children are snotty. A research study that tested children for multiple respiratory viruses every week for a year found that under-fives are carrying one or more viruses 50% of the time.

If parents feel their small children are sick with a cold half the time, that's backed up by evidence.",
