Supporting backup documents to relation?

[visa_time]

My mom has CP interview and I already submitted my original
birth certificate of affidavit done by my mother.

Just in case, at the time of interview, if consular asks more proof,
what should we carry for interview? photos showing my mother with me?

Any other doc I should be asking her to take?

Thanks.
