They are quiet...now

So...last night was really weird. My children did something they never have done before. It baffled me. I was sound asleep in bed...it was 3am...I heard some giggling and thought, surely not...so I got up and slowly made my way to the girls room...sure enough, the girls, ALL three of them were giggling and playing, like it was mid afternoon! I couldn't believe it! I immediatly shot them the mom look and they took off at maximum speed into their beds...but it didnt end there. I went into their rooms to tuck them in and explain it was still nighttime and they had food hidden in their beds! Pringles and popcorn! I wonder just how long they were up?! I had to confiscate all the food and then I headed back to bed...3 minutes later...giggling...jumping from bed to bed! I was tired, Shain was tired, but he stood up and made his way to the girls room where you could hear the scrambling feet and the nervous noise. After a couple spankings each(yes we spank for defiance) they were all in tears and then quieted down nearly immediatly. Not another sound....until 7 this morning, which to me, was tooooooo early for Saturday. So when or when will they finally appreciate sleep?!
