Breast milk for Diaper rash??

Ma

Has anyone help that breast milk will cure a diaper rash? My son developed a rash from diapers a family member bought for him and my aunt told me to put breast milk and that it would cure it..I breast feed but I’m not sure about putting it on there without other suggestions from moms who might have tried this..He has a yeast infection and I’m afraid of irritating it even more☹️ Any suggestions??
