Running around and acting silly is a natural part of being a kid, and as such, so is getting hurt. Obviously, no one wants to see children in pain, but many parents and educators learn to accept the fact that it’s bound to happen sooner or later.

The problem arises, however, when minor injuries get improperly treated—or go untreated altogether. Just because a tiny scrape seems as if it’s nothing to panic about, that doesn’t mean that it shouldn’t be taken seriously.

That was the problem that 3-year-old Abbi Holland ran into when she got a small scratch at school. What happened next forced her parents to rush her to the hospital.

Three-year-old Abbi Holland from the U.K. tripped and scraped her knee while playing on her school’s playground. Staff at the school thought that they had done everything they could by cleaning up the scrape with a moistened paper towel, but they couldn’t have been more wrong.

Mere hours later, Abbi developed a fever of 109 degrees, and was subsequently rushed to the hospital by her parents, Dave and Caz.
