my little one s 40days old... he was born fair and was same till 15days. my hubby hv exposed him to sun few days as he had mild jaundice. .. he slowly got dark now ..my doubt s if it s his complexion by nature it's ok.. but if it's damage due to direct sun exposure ..will it get set naturally and will it back to his complexion again? my elder son is fair and we parents are wheatish completely .. pls advise
