Teach polite words early
Even two-year-olds can learn to say “please” and “thank you.” Even though they don’t yet understand the social graciousness of these words, the toddler concludes that “please” is how you get what you want and “thank you” is how you end an interaction.
At least you’ve planted these social niceties into your child’s vocabulary; later they will be used with the understanding that they make others feel good about helping you. When you ask your toddler to give you something, open with “please” and close with “thank you.”
Even before the child grasps the meaning of these words she learns they are important because mommy and daddy use them a lot and they have such nice expressions on their faces when they say these words. Children parrot these terms and understand their usefulness long before they understand their meaning.
