For video brief kids getting messy.

This adorable video shows what happened when two toddlers were left on their own - they covered their entire faces in cream for NAPPY RASH.

Pupae Anawach, 27, was in the living room getting sons Merce, 3, and Marwyn, 1, ready for bed but popped into the kitchen for a glass of water in Chicago, Illinois.

She made a quick snack and returned a few minutes later to find the two boys had opened a tub of prescription ointment for nappy rash - and smeared it on both their faces.

Their pajamas are covered in the lotion - as well as the floor - and Pupae is heard saying to them ''go to the bathroom now... the cream is all finished now.''

But Marwyn looks out innocently with his face and head covered in the white medical ointment - and turns away smiling to carry on playing.

While older brother Merce is caught white-handed with the gooey lotion all over his hands - and they both burst out laughing while refusing to go for a wash.
