Allow the diaper area to be exposed to air at times when you are home. Don't always cover with diaper. Let there be period off fresh air just blow the area. If you do this, most diaper rash will disappear. Any rashes that persist especially if Reddish, forming Discolouration etc needs attention of a Paediatric Dermatologist.

2) Apply diaper cream - vaseline, Sudocream, shea butter, zinc oxide cream are fine. Do not apply Powder pls....it must be something that creates barrier between skin and urine. Powder will be formed into paste by urine and further irritates the skin.

There are 2 different types of nappy rashes in broad categories. Those due to irritation from the urine and diaper and those rashes that tend to occur in the nappy areas. It takes a Paediatric dermatologist to differentiate. What you can do as Mums?... First assume it is a diaper rash from prolonged contact of skin with urine. So change the diaper frequently when wet not only when there is a poo.
