Once you’re past a certain height and weight you really should not be attempting to sit in those swings made for babies at the playground. The South Wales Fire and Rescue in the U.K. tweeted out recently, “We have released two teenagers from baby swings this evening. If you are over age four please don’t try to get in one!! It may hurt when our crews try and get you out. These calls delay our fire crews from other emergencies.” It turns out it's another internet “challenge” that is driving the behavior as teens film themselves getting into the swing and post the footage to TikTok.
