Child-friendly, simple explanation of what a bruise is, a corrected grammar version of the sentence, and easy steps for a 6-year-old to understand what to do when they get a bruise.
A bruise is a dark or purple mark on your skin that can appear after you bump into something or fall. It happens when tiny blood vessels under the skin break and a little blood leaks out under the skin.
When you bump your arm or leg, the tiny tubes that carry blood (they are called blood vessels) can get a little hurt. Some blood goes under your skin and makes a colored spot called a bruise. Bruises often turn different colors as they heal.
If a bruise is very big, hurts a lot, or you get bruises without bumping into things, tell a grown-up or see a doctor.
