While activity helps to build a child's appetite, plan a quiet time before meals and snacks. Kids eat best when they're more relaxed. Remember your child learns by watching you. Eat with your kids. Set a good example by eating a variety of foods yourself.
Older siblings can have a similar effect.
So make healthful eating a family affair. Eating together is also a good chance to demonstrate appropriate table manners. Young children need supervision in case they start to choke. Someone who's choking may not be able to make sounds you can hear easily. Encourage kids to sit while they eat.
