== Deshsthas and infants! == 

 There are no death rituals specified in Vedas for dead infants.The dead baby is fed milk,and is then buried according to the Shastra.Salt is sprinkled on the soil,and the dead body is wrapped in a cloth and then buried.No cremation or Agni Sanskar is devised if the dead infant is less than 26 months old. 

 (Above statements have been extracted from the book  Antyeshti Karma Sanskar Paddhati,and I have translated them in English) 

 So I would advise you to do some more research on Antyeshti of infants in Deshasthas.All the Brahmin ans Brhamin related high castes do not cremate the infants.
