Have your husband read this:

Couple of ideas:
For the child, see what consumables you use per day. Then you will have an idea of what to budget for the kid (I am not a parent so this is the "unknown but try to quantify" within me). Also begin researching on hospitals in the vicinity and other places just in case, you know where to go (once again, I'm not a parent but I do this on trips because accidents/illness happens to ANYONE so knowing is easier than figuring it out).
Shakedown runs (local camping/trips) before is a CAPTIAL idea. Somewhere your husband is familiar with is always preferred. The problem initially is that you pack too much crap. I know I did it. I had a giant truck and even with only me in it, I would have it slammed full of crap. It took a while to fully understand what I NEEDED and what I didn't. This came with practice. I learned that if you bring a bunch of little items that are "spares", then it adds up.
At the hardware store, there is this stuff made for your lawn to keep bugs away. You sprinkle it on the ground. I would research this.
My husband and I did read that thread about getting a non-outdoorsy woman into overlanding. It does have some useful information. Your suggestion about the average number of consumables/day is terrific. I do this for the diaper bag items already, but I am going to start with everything else including my stuff and my husbands. I really appreciate all the effort you put into your response. We are going to do some dry runs around here to test ourselves and our equipment. Thanks again - can't wait to post pics of the actual adventure!
