Cleaning pubic area of a baby

I am a mother of 18 days old baby girl, I want to know how can I clean her pubic area? There still some white material at the inner sides.

 

It is normal for a newborn to have some white material along her vulva. Gentle washing with a gentle soap and water should be enough. Please do not do hard scrubs, since those can damage the infants delicate skin. This should clear up in a few weeks.
