Hi My Son Is Almost 4 Months Old Now, And

Hi my son is almost 4 months old now, and I want to start feeding him the normal milk , preferably Amul milk to him because I work late till midnight and won't be available to feed him. I usually top feed with formula milks but he wasn't satisfied with those artificial milk forms. Please tell me, milk from Amul, mother dairy etc is safe for the child or not , as I heard lot of horrofic stories regarding how they adulterer the milk with detergents and so on... I know breastfeeding is best but I have to give him top feed once a day
