1. A child's appetite depends on many factors like age, genetics, season and can vary significantly between children of the same age and size. 2. It is normal for children to lose their appetite for weeks at a time and forcing them to eat during these periods can cause food aversions. 3. Mothers should offer a variety of healthy foods and let the child decide how much to eat rather than focusing on appetite or forcing food. As long as weight is normal for age, appetite is also likely normal.
