My wife is absulotely great at helping out while backing. She and my son are both really good, and I trust them both 100%. Weather it be backing up to the hitch (gooseneck for me), or backing up the trailer, we all seem to get along, and get it done. We have a 36' tri-axle and there are many times that you can not do it by yourself, and the extra set of eye's are needed. I think most of the guys that try and leave there wife's out of the "loop", are missing out. If they would take the time and explain what they need from them in the form of signals, they would have a much better time. I think most of the women, would like to help, just they don't like to be yelled at or put down. Maybe just a few minuets explaining what it is that you are trying to do, and what you need from them, would have everyone working in the same direction.
