Hi...don't worry if the kid is active and developmentally normal. I take this opportunity to tell you certain scientific facts and relieve your distress -
An active is a well kid even if she/ he is not eating well. Development of a kid is as important as or I would say even more important than growth alone. As the kids grow their interest in food decreases and interest in play activities increases so that they eat small quantity and run away to play. As parents we need to be more patient and feed than less quantity but more aliquots per day. This age rather than the quantity of the food I suggest you concentrate more on the number of times you feed her and also make whatever you feed her calorie dense by adding good amount of ghee to it. I suggest you not to use appetite stimulants on long run as they may cause drowsiness.
