A babysitter’s shocked reaction to an unexpected confession from a child she was watching has gone viral on TikTok. In the TikTok video, user Caroline Mackenzie shared a clip with on-screen text describing what happened while she was babysitting. “The little girl I’m babysitting just said, ‘I have to tell you something. My mommy told me not to tell you,’” the text read. For many TikTok critics, that guidance underscored why they felt so strongly about the babysitter being kept in the dark.
