A three year old child should be encouraged to eat 6 small meals a day. Children are not like adults; they have smaller stomachs and do not hold as much food as grownups do, therefore, they need to eat smaller, frequent meals. They need to eat a balance diet of all four food groups. Check with your health department for the guidelines and how much of each portion they should have. Make food fun for children, not a punishment or something bad.
