Butter wouldn't melt in this cutie's mouth.
Her dad Jesse Mab-Phea Hill, from Omaha, Nebraska, in the US, might disagree.
As his daughter, Alessandra, napped he enjoyed some downtime.
Popping upstairs, he smelt 'something foul'.
'I run up the stairs screaming no, no, no, no, till I get to Alessandra's room.
'There she is, standing at the baby gate, butt naked, holding her diaper, covered head to toe in her own crap.
'I'm not talking a little poop here and there on her. I'm talking layered on globs of human fecal matter covering her arms, legs, face and HAIR. It's bad.
'It's worse then any other time she decided to explore in her diaper.'
After cleaning up the 'category 5' poop explosion, Jesse recounted the ordeal on Facebook.
