What else to send with RFE?

[verwen 33]

Other evidence (as well as one photocopy of each document presented) which will help establish that beneficiary's biological mother's relationship with beneficiary is bona fide, and as a result, that beneficiary's relationship with petitioner is bona fide. Examples of other evidence....... So we got all we could get to prove a relationship between my wife(beneficiary) and her son(beneficiary), just wondering if we send just the new documents or do we need to send everything that was in the original I-130 packet also?

Only send what is specifically asked for unless there was something you forgot to include with the initial submission but wanted it to be in the file.

Thank you, so no need to send his birth certificate again?
