What IS it with my kids?

So, I'm at home the other day, and I can't find Brynn. It's about 4:30 (and we have dropped her afternoon nap, I should add), and the house is just too quiet, which always beckons the question, "Where's Brynn?" I am running around the house calling, "Brynn, where are you? Answer Mommy!!" I do this for what seems like eternity (really only about 10 seconds), but I am starting to get really panicky! I walk into Asa's room, and I just happen see 2 little feet sticking out from behind his crib. I go to look closer, thinking maybe she's playing hide and seek. But no, you guessed it, she's fast asleep behind the bed. What IS it with my kids??? (If you read my "Sound Asleep" post from September, you know what I mean!)
