If your child is underweight, it’s important that your child gains weight in a healthy way, and this means eating a balanced diet which is three meals a day and healthy snacks. To help your child gain weight, increase their portion sizes at mealtimes, especially for starchy foods such as bread, rice, pasta and potatoes. If your child isn’t consuming enough calories, you can boost their daily intake by providing healthier snacks, such as dried fruits, small sandwiches with cheese or eggs, bananas, etc. Even if your child is underweight, it’s still important that they’re physically active. Physical activity helps them develop strong, healthy bones and muscles. Keep regular records of your child’s height and weight. Once your child has reached a healthy weight, their diet may need adjusting so that they don’t become overweight.
