It was quiet in the house (never a good thing) and I suddenly heard, "Help, Mommy! I 'tuck! Help!"
I went to investigate & found Wendy climbing the stairs - which she has no business doing - on the OUTSIDE of the banister. Her little toes were clinging to the one-inch carpeted ledge, and her little hands were on the top of the rail.
Fortunately, she was only two steps up before she decided that was a bad idea.
