Boy, I've been there before!! And, funny enough, my husband was traveling as well. I read every book, talked to DRs, asked around, and the concensus (that did end up working) was to let it be. It was his way of having a say! That doesn't mean it's totally fine for him to add all this etra work and trouble for you. Not at all. And when he did need my help, I always had him help me do something else after to help make up time, in a sense. He didn't seem malicious at all, just non-chalant and la-dee-da about the whole thing. Every morning, I would (very cheerfully) ask him if it was a diappy or undy day. The days that HE chose completely on his own he was just fine. The days I encouraged underwear, he always had his accidents. There were some eceptions, but overall, this is how it worked. We were also very careful not to attach negativity to wet pants at all. He was in charge of "fiing" the situation (changing pants, using dienfectant wipes to clean up, bringing down sheets, etc). I (again, cheerfully) made it lots more work to have an accident than to just run in. When he did wet his pants, he lost the option and had to have a pull-up(diapy). He didn't always act like he cared, but I think he did. The other thing I heard over and over is that the physical negative responses (spanking) will definately make the situation worse. I know every kid is different, and every family is different, and being a part-time single Mom, you have to do what you can, but that's what worked for us. Oh, he does still occasionally wet the bed at night, but his DR has already told us there is a small bladder and sleep pattern issue, and to epect that. Good luck!!!!
