Critical Thinking?

When amongst ones own peers we assume they are at the same level of understanding as us and so when we explain something there is no second thought as to how we choose to explain it. This is not so much the case when it comes to smaller children. You do not necessarily have to choose what you say carefully but HOW you say it. This was not something entirely new to me but it has become more frequent due to the fact that I am with the children full time. I have to say, it's fun, having to think of a way a could would think. More easily said than done because an explanation is typically followed by a rebuttal of  questions.
