I hate doing things twice also but think about, how many times you gotta change a baby's diapers and that chit stinks!!! 
I doesn't take soft ground. I have a rack on a concrete pad and had the outside row come over. It was all Beech. It just doesn't stack that great. Something settled. I ended up re-stacking the whole rack. It happens.
As a new father I gotta disagree on that! For some reason my little girl LOVES having her diaper changed, it's the one thing that's guaranteed to take her out of a screaming fit and put a smile on her face immediately. I honestly look forward to changing her diaper, there's something about her looking up at me, smiling and jabbering 3 month old nonsense that makes my day!
Here it is the wind. In bad winds I have had 3 or 4 stacks blow over at the same time. They will start to lean from shrinkage and I will take a split from the top and pound them back up straight. I have taken some pallets and braced them against the wind and that has seemed to help out a lot so far.
You obviously aren't that adept at wood stacking yet.......................you need more practice!!!:stacke::stacke::stacke:
Same thing with my lil one! Actually, that ended up being our obstacle for potty training. She had no problem using the potty, but did everything she could continue getting her fun diaper change times.
Brand new woodshed, didn't even get the 2nd stack done before I found this one morning. I almost cried.....
So maybe you could record your little girl's "happy diaper change" jabbering, and play it over the loud speaker when re-stacking your wood? Just a thought, bud.....
I think anybody in a dirty diaper would want to have it changed ASAP. Not only babies, but the nursing home crowd as well.
