Hi, Poor appetite in children can be a concern and it is important to identify the underlying cause. It seems like your daughter has been suffering from recurrent respiratory infections and this may be affecting her appetite. In addition, her weight has not been increasing which can be a red flag for growth and developmental issues. It would be advisable to take her to a pediatrician for a comprehensive evaluation to identify the root cause of her poor appetite and recurrent infections. The doctor may perform tests to rule out any underlying conditions such as allergies, infections, or gastrointestinal issues. In terms of treatment, it is important to focus on providing a balanced and nutritious diet to promote weight gain and strengthen her immune system. You can try offering small, frequent meals and snacks throughout the day to encourage eating. You may also try offering a variety of healthy and colorful foods to make mealtime more appealing to her. A healthy tonic may help provide additional nutrients and promote appetite. However, it is important to consult with a pediatrician before giving any supplements or tonics to children. In addition to dietary changes, it is important to maintain good hygiene practices to prevent infections. This includes frequent hand washing, avoiding contact with sick individuals, and keeping her environment clean. Overall, it is important to address the underlying cause of poor appetite and provide a supportive environment to promote healthy growth and development in children. Take care.
