Kids love juices. However, the store-bought variety is sugar-laden, which would only make them put on weight. Use natural, low-sugar fruit drinks or make your own juices at home. Make healthy, vitamin-packed juices, freeze them in small bottles and pack them along with the children’s lunch box. You can also freeze a half-filled bottle the night before and top it up in the morning. This way it will slowly thaw out during the day. To avoid condensation and moisture, pop it in a plastic bag.
