It was early in the morning when I made myself a cup of tea and put it on the table to cool. Our 2-year-old daughter had spotted the steaming cup and almost immediately I
heard an awful cry. I quickly turned around to see her dropping the cup. Her arm was steaming. She had poured the whole freshly boiled cup of tea over herself.
Instinct (直觉) kicked in. I quickly took off her clothes because I could see it not
sticking to her skin. Seeing her arm turning pink, I just kept thinking: why was I not
watching her Luckily, my husband, having taken a Red Cross first aid course recently,
knew just what to do. He placed my daughter’s arm under cold running water while
comforting her. I could see my precious little girl’s arm bleeding. I knew I would never
forgive myself for not moving that cup out of reach. It didn’t take long for the ambulance to arrive. They told us we had done the right thing to save her from even worse burns.
Through this terrifying experience, I knew learning the right first aid actions could truly make a difference to saving lives.
