Are you trying to teach your child color names? Paint her nails with the specific color you’re working on (such as red) and declare it a “Red Day”. All day long, point out objects in her environment that match her nails, and encourage her to do the same. Wear red clothes, add red foods to mealtime and use a bath color tablet to make her bath water red. Once she’s mastered that color, paint her piggies a new color.
