Every day will be a new experience as you explore and learn the colors. This activity is a great way for your child to celebrate the colors as they try different kinds of food and learn about new objects. Has your child ever had key lime pie yogurt? This will be a hit on the day you celebrate green. When it's red day, you could sport your favorite red attire, eat red delicious apples, paint a fire truck, count all the items in the room that are red, and even make a list of your favorite red things.
