Bad word

Did someone say.....nap? I have learned over the past few days that this is a very bad word. Nicky never, ever wants to 'need a nap'. It's perfectly fine to 'want to go to sleep', to 'need some sleep', to 'be tired' or to even get 'put to sleep'. However, he never needs or wants anything to do with a nap. Nicky will actually wake back up to give you a dirty look if you utter any phrase with nap in it. I'm not sure why naps are negative. It reminds me of "Honey, I Blew Up the Baby". Remember that movie? The 20 foot tall toddler would throw a fit at the very mention of the word nap. This must be something that comes in the toddler handbook because I don't think I've ever used this word negatively. Very interesting.
