WHen it gets quiet........

Ok so Ellie is mischevious and when it gets really really quiet I start becoming concerned. Today I put her down for her nap and usually she gets out of bed a few times or I can hear her flipping through her books but today was different....... today was quiet. I put Lucy down and snuck into her room and found that she had crawled into Lucy's crib, then up on to the change table, got the pennitan and was proceding to smear it EVERYWHERE!!!!
