At a young age, cleaning a child's plate should not be a requirement. Kids have an amazing ability to listen to their hunger and fullness cues; in fact, much better than adults! So making a child eat more than he or she wants can lead to unhealthy eating habits later in life.
Kids don't dehydrate like adults, so don't encourage sports drinks at a young age. They are not professional athletes with adult needs. Stick with water.
Gaining weight will happen during puberty, so don't give your kids what they want all the time.
