Serve a wide variety of colourful vegetables and set a good example by eating your vegetables. Cook vegetables until just crisp, or give them raw in a platter with dip. Try them in soups and casseroles. Children also love to eat vegetables they've helped to grow or prepare. In the meantime, relax and serve a variety of fruit for snacks and desserts.
Fruit offers the same nutrients as vegetables.
My child often drinks a glass of milk and leaves the table. Milk is an excellent food, but not perfect - no one food group can supply the nutritional benefit of a diet that includes all four food groups. A glass of milk can satisfy the appetite of a busy preschooler as well as filling up his stomach. I've heard that many preschoolers don't get enough. Iron deficiency is a problem for some preschoolers.
