Im in the weak stomach club. Especially when it come to foul ordors (although im getting used to skunk odor). This is terrible, but Im going to tell it any way.
I always refused to babysit for anyone until their kids were potty trained. Well finally our twin nephews where old enough. They were like five I believe ( this was about 12 years ago), and me and James were going to keep them for the day. Well, as it turned out, one of them had an accident in his pants.
I imediately started to gag. James was out in the pasture. I couldn't get ahold of anyone to help me and I knew that the poor boy needed to be cleaned up and a fresh change of clothes.....
James came driving up to the house on the tractor and said " what in the heck are you doing?"

.... I had our nephew out in the yard, stripped off and I was hosing him down with the water hose, from far enough that I couldnt smell anything.
I hosed him down and then I hosed his clothes down, and then I put him in a big bubble bath.
James was just shaking his head. I told him that I cant help it. I was fixing to puke and didn't know what else to do.
