Coconut oil to treat nappy rash

Bare Naturels Cosmetics Coconut oil

So my youngest daughter has just turned 1 and we transitioning from formula milk to cows' milk. I have not yet quite figured out why but this just seems to coincide with the onset of nappy rash, it happened with my first daughter as well.
At the first sign of bum redness out comes my Extra Virgin Organic coconut oil (Supplied by Bare Naturels Cosmetics). I apply the coconut oil directly to the affected areas. Coconut oil works well to treat mild cases of nappy rash.
Of course if the nappy rash is severe consult a doctor.
