why my 6 month old baby skin color will be dropped and her private parts getting darker and below neck also getting black why so and what's the solution for it.

A. Hello dear parent! Maintain a good personal hygiene for your baby. Regularly massage your baby with any oil for better skin care. Give your baby a well balanced healthy diet and keep hydrated all through the day. Continue breastfeeding your baby till one year completion. Good luck and take care.
