Please also 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 need attention of a paediatric dermatologist.

I will advise you first assume it is a diaper rash from prolonged contact of skin with urine.....so 1) change diaper frequently when wet...not only when there is a poo 2) Apply diaper cream - vaseline, sudocream, shea butter, zinc oxide cream are fine...NOT 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.
