If the child is overweight, teach them healthy eating habits. Rather than restricting the amount of calories they take in, or restricting a food group or a favorite food, it's better to help them develop some sound eating habits with a balanced diet. Families don't eat together often and they tend to snack constantly. We don't need to cut out snacks completely but have scheduled times when the snacks will be available, and then have some healthy foods for the children to choose from at those times. Parents should establish regular meals and snacks for the whole family.
Exercise is also very important.
Try spending more time playing with your child. This could include bike riding, walking, jumping rope or participating in an organized sport. It's really important to be careful what we say to children with regard to weight. Children can interpret a negative comment from a parent to mean the parent doesn't really love them, or doesn't accept them for how they look. It is important for their self-esteem to feel loved and accepted for who they are, not how they look.
