Relatives can push food on children. Usually they do this to show affection.
Your child should deal directly with food-pushing relatives. These relatives need to understand how your child feels. Give them a chance to help your child learn how to confront food issues.
Try role-playing with your child so she can practice dealing with someone who pushes food. Encourage your child to ask relatives for help.
For example, your child may say, "Grandma, maybe we could go for a walk instead of having cookies and milk." Most relatives are willing to help when a child asks.
