I shouldn't have known

Mark took the side rail off of Molly's crib this past weekend.  She's been doing really good in her "new" bed.  She's taken naps and slept all night long.  I've repeatedly told Morgan NOT to encourage Molly to get out of the bed, and NOT to show her how to climb in and out.  Well wouldn't you know it, she figured it out on her own.  We were playing in the room yesterday afternoon and she climbed right in to get a book and slid right back down to get out.  Then this morning, I was in our bathroom and Morgan came in.  Not unusual.  But the sneaky little look and the shuffle of little feet was unexpected.  Sure enough, Molly popped her head around the door and gave me a HUGE "Mor'ing Mama".  Little stinker.
