I am taking care of my 2-year old niece, she is very aggressive in eating. You can always find her in the kitchen whenever there's someone eating. The problem is, she ignores rice and she eats most of our dish. Usually our food is only limited for the whole family. I cannot control her with this, she'll not stop until she saw the plates emptied. How can I possibly control her in consuming most of our dish and ignoring the rice?
