Teeth and sleep crawling

my life as I know it is over. the Princess has her first tooth (well it has broken the gums) AND she has mastered crawling. In her sleep. Yup not a typo. She sleep crawls. *laughs* she won't while she is awake but in her crib durring her nap she motors it is funny I am going to have to video that. Has anyone else heard of sleep crawling? I think that is the most bizarr thing any of my monsters has done. (keep in mind Boo is in a pirate phase and is wearing a Louis vuitton silk scarf on his head as a pirate bandana at them moment and Landon won't take off his tigger halloween coustume :P)
