It is not clear from your explanation which is the Parent and which is the Child but typically you have a relationship where one Parent has many Child records.
Then any field do you want down on the child record to simply go to that relationship and add look up Fields on the relationship. Then any changes on the Parent will be instantly reflected in the children records.
So you are not auto populating existing fields in the child record you are bringing those fields down is look up fields.
