Am planning to buy a bunny alarm clock to try to persuade my 2 3/4 year old ds not to shout 'I'm awake now mummy, get up!' at 6am. Has anyone tried them and found they do/don't work? And if so, does anyone have a discount code for letterbox or gltc, as I really object to adding 4 or 5 pounds postage onto the £20 cost so any help gratefully received...
