Kids start developing their sense of self as babies when they see themselves through their parents' eyes. Your tone of voice, your body language, and your every expression are absorbed by your kids. Your words and actions as a parent affect their developing self-esteem more than anything else.
Praising accomplishments, however small, will make them feel proud; letting kids do things independently will make them feel capable and strong. By contrast, belittling comments or comparing a child unfavorably with another will make kids feel worthless.
Avoid making loaded statements or using words as weapons. Comments like "What a stupid thing to do!" or "You act more like a baby than your little brother!" cause damage just as physical blows do.
Choose your words carefully and be compassionate. Let your kids know that everyone makes mistakes and that you still love them, even when you don't love their behavior.
