As the host of her own Food Network show, a nutrition expert and mother of two boys, Robin Miller knows all too well the mealtime struggle many parents face. She shares her strategies to ensure children get the balanced diet—rich in protein, whole grains, fruits and vegetables—their bodies need.

One way to make sure your little one is eating a variety of healthy foods is by imagining her dinner plate has a peace sign drawn on it, Robin says. Fill the larger areas with whole grains and fresh vegetables and fruits and the smaller area with protein. "This balanced 'peaceful plate' allows you to put a variety of bright colors and flavors on the plate and ensures you child is getting the right balance of essential nutrients and foods from all food groups," she says.
