Do you know what I thought the first time M did it? Oh shit, she must be getting ill, she's clearly too poorly to wake up and bed hop at 2am. Nope. It just happened. And a couple of months later, she sleeps till 8am every morning, doesn't wake much and if she does, she rearranges her ninja turtles and goes back to sleep. I've been praying she'll be sleeping through before school starts and it happened suddenly. Have you been ridiculously effusive with the praise? I think I might have offered dd a pony...
