Little one still asleep.
Oh yes, small child. I shall teach you the ways of uber napping. You and the nap shall become one. Ten minutes is now pointless - you shall join me, your master, in experiencing the pure joy that is a 4 hour sleep in the middle of the day. Sure, you may not sleep tonight but then again it's purely a case of "not my child, not my problem". Followed by much lol'ing at my sister's expense.
So sleep, my teeny niece. Sleep and forget about everything else. Shhh....
