It has been said that we're always teaching sometimes we use words. Remembering to say "thank you" is proper. However, your child is watching you: the first and most influential teacher! So be sure to live a life of gratitude. When you model thankfulness, then your child will absorb that teaching.
Notice Nature
Encourage your child to appreciate the inspiration that surrounds her. Marvel at the power of the wind, the immensity of the ocean, the perfection of a snowflake, the endless night sky or the rugged beauty of a mountain range. I've reminded my girls of the saying of Goethe, "Nature is the living, visible garment of God."
Convert Attitude into Action
A small gesture, such as a smile, can lighten the day of the waitress who hands your youngster a glass of milk. A hug for your child's teacher is another attitude action. When she empties the dishwasher, remind your daughter that this is her action of appreciation for home and food even if she doesn't think so at the time. Thankfulness can also be expressed through homemade goodies. To show appreciation for their classroom teachers, my girls and I made little holiday gifts for them. What ways can you convert your thoughts into action this season?
Discover Dictionary Descriptions
Although we have our own words to explain thankfulness, it helps to see new definitions. Go to your public library and see what dictionaries say about the word. I like what Webster's Dictionary says about thankfulness, "Impressed with a sense of kindness received." This definition takes the focus off material possessions and puts it on the giver.
Gather Great Quotes
My research for this article took me to Web sites that offer all types of quotes. A humorous one about thanks comes from Woody Allen: "I am thankful for laughter, except when milk comes out of my nose." Have fun with your child as you gather quotes about thankfulness.
