Naptime???

I put Sabrina down for her nap, and for the next hour all I hear is "mum mum mum blah blah blah blah" thump thump "mummumumumumumumumum MUM MUM MUM blah blah blah blah" thump thump jump jump jump jump jump "MUM MUM MUM MUM MMMMUUUUUUUUUUUUUUMMMMM AAAAAHHHHHH MUM MUM MUMUMUMUMUMUMUMUMUMUM AAAAAAAHHHHH". She kept calling my name, jumping, throwing toys out of her crib and talking to herself. When I finally went to check on her, this is what I found...

That's not how I put her to bed...
