Words of Encouragement and Praise

Children thrive on positive attention. Children need to feel loved and appreciated. Most parents find that it is easier to provide negative feedback rather than positive feedback. By selecting and using some of the phrases below on a daily basis with your child, you will find that he will start paying more attention to you and will try harder to please.
