A. Hello father as far as she is active for the age and also eating healthy not to worry on that .. some vairation is acceptable . though you can add ghee to her meals , dry fruits & nuts can be given as snack or added in certain foods. panner , curds , fresh fruit milk shakes , eggs , stuff paranthas , soyo , sago etc
