If you do have a referral, include a picture and a nice note that this is your child and anything they can do to rush your paperwork would be so very greatly appreciated. It can't hurt for the person to at least see a face. I've heard of people adopting a waiting child from China that did this and it seemed like their local USCIS actually did process things quickly for them. Sometimes seeing the face behind the paperwork can pull some heartstrings.
