Think about how often we tell our kids no. Before I realized that saying, "Yes" was a parenting tool, my default answer to my kids was usually, no. Why was my answer always no, probably because it was just easier to say no.

Practical tip: I buy the big bags of Life Saver mints and keep them in my car. All of my kids know that when they get into my car, if they ask me for a mint, I will say "Yes." The only rule is; they have to ask. As long as they ask, I have always been able to say "Yes." This is a very easy way to implement this parenting tool. Customize this tool to what your kids like or steal this idea, it works great.
