"Goodness me. What on earth is that smell?" Uh oh! You let a messy drop in your nappy while you were dreaming and you didn't even notice! Now you're rolling around on your back feeling the cold mess mush into your bottom! Oh you think Mummy is going to change you right now? I don't think so! This will teach you a lesson when you argued with Mummy that morning that you were too big for nappies and you didn't need them anymore. Imagine if Mummy had sent you to bed without a nappy on and you made a dirty mess of the bed? No no! I think you need to learn a lesson about being a cheeky boy!
