If a parent starts with this attitude, then by that posture, he blinds himself to any growth of knowledge that there might otherwise be. First, he would take the view that if the baby is clearly not happy with the situation, there must be something wrong. If the baby is objecting a lot, then there must be something badly wrong. So the rational parent would be making great efforts to find a solution. Or maybe she doesn't want to wear nappies at all.
Parents often talk in terms of conflicts of interest.
He wants me to read stories, play games, and generally give him attention, and he bugs me about it for hours every night. I don't object to giving him attention at weekends, but during the week, I think he should be in bed when I get home, because I am just too tired to play with him. It utterly fails to account for new ideas, real solutions, discovered through human creativity. First, I should point out that this whole conflict would have been much less likely in the first place if the parent had behaved more rationally when it was first beginning to arise. Well, he would not see the answer as being one of only the two initial conflicting ideas.
