  • The child should never be force-fed or scolded or beaten. Instead, he will lose interest in eating. Eat with encouragement and praise.
  • The child needs to be given a light snack twice in the morning, noon and night. But do not force food from time to time. Remember, breakfast should not be given at a time close to the main meal.
