don't drink "that" gatorade

We drove down to Queen Creek this afternoon. Colby met us just before we left town to say goodbye to the boys, as he was not coming with us. He gave each of the boys their own gatorades to drink on the way down. I knew exactly what was gonna happen so in an effort to avoid five different potty stops I told them not to drink it all at once. By the time we were at Cordes Junction, gatorades were gone and Blue was shaking like crazy because he had to go the bathroom. I made him hold it till Black Canyon City (another half hour). When we got into Phoenix Reed needed to go. Blue's potty break was only about twenty minutes earlier, why didn't he go then? He said he didn't need to. Of course. We were in the thick of rush hour traffic and I was not stopping not to mention it gave me the opportunity to give a few "I told you so". Reed was really going crazy now.
I had heard from one of my sisters that she makes her boys pee in bottles while traveling. So I thought I would offer this option to Reed, thinking that he would never go for it. He is my rule follower and surely there is a rule somewhere about peeing in a bottle in a car. Much to my surprise Reed agreed to this option. It must have been pretty thrilling for him because not more than 20 minutes after filling the first gatorade bottle and he "just" had to go again. As disgusting as it sounds, it is very convenient and I think I will use this option in the future.
