In fact, communication skills can decrease aggressive actions, like biting, when the problem underlying the aggressive behavior is frustration over not being able to communicate a need or want. Contrary to what most parents might believe, children want their parent's approval, especially at an early age. A child's self-concept is determined, to a large degree, by what a parent says and what a parent does to their child. A child who is valued, in word and deed, will have a good self-concept while a child who is mistreated and ignored will not. Reflections are an excellent way for parents to ensure that their children have a good self-concept.
Reflections operate in a similar fashion to a mirror.
Just as a mirror reflects your physical image, a parent can reflect a child's emotional image. Knowing what we look like is difficult unless you have some reflection to determine our shape, color, and form. Children, similarly, do not know how to feel about themselves without some feedback and description. But children are not looking for physical descriptions. They are in need of emotional descriptions.
