Not as witty as the one I lost but oh well...

A cup of coffee placed on a knee high book shelf...

A distracted mother turns her back for a moment to check Facebook...

A curious baby finds the coffee mug...

A frantic mother zooms to the other room to get a towel...

A free-range baby finds a basket full of diapers...

A kicking-herself mother reminds herself "not to cry over spilt (coffee) (diapers) (milk)"
