One thing my kids like to do is snack! I've had to get pretty creative with tricking them into eating a variety of healthful foods, but it often works. One simple thing was taking my pediatrician's suggestion to wrap a spinach leaf around a baby carrot. The kids already loved carrots, and surprisingly, they quickly began liking spinach, too!
Another simple snack for toddlers all the way to big kids is to let them go fishing. On a plate, place a dollop of peanut butter along with some fish-shaped snack crackers. Then you can get creative with "fishing rods". I've used pretzel sticks, celery sticks, and carrot sticks. They use the sticks dipped in the peanut butter to pick up the fish crackers. To make it even healthier, substitute or supplement the crackers with small cheese cubes or diced fruit.
