Courtney and bedtime

Courtney is my night owl. We usually put all of them to bed around 7:45-8:15. Courtney is usually very quiet and "reads." All of the books are slowly moving to her bookshelf. Well last night she was up doing stuff and making noise. Jon went up a couple times and told her to get back into bed. Around 9:30 he says to her "if I have to come back in here one more time you are getting a spanking." which she replied "Then dont come back in here!"
