2y/o chewing on electrical cords- how can I explain to her that this is a Really Dangerous Idea?

My 2y/o really loves shoving things in her mouth. Like my keys. Or her other mum's wallet. For the most part, I take them off her, and explain that whatever-it-is isn't made to go in mouths, and might be made out of chemicals that could hurt her or make her sick.Last night I caught her behind the settee gnawing on the electrical cords there. I pulled her out, sat her on my lap, and said: 'You will get very hurt if you do that. It will be the worst hurt ever. You will hurt all over your body. Your head will hurt and your tummy will hurt and your feet will hurt. It will make you very sick.' Then I wouldn't let her off my lap until she could tell me why she shouldn't eat electrical cords....Naturally, later in the evening the electrical cord was back in her mouth.How do I make the lesson stick? via /r/Parenting http://ift.tt/2fT7Nys
