Krishna supply all our necessities

The child is born ; immediately there is milk in the breasts of the mother. And one minute before, there is no milk. Just the child is born, immediately. Who supplies the milk ? He does not see that one Supreme is supplying all the necessities of the others. So our duty is only to become Krishna Conscious. Other things will be supplied by Krishna.
