I found a canadian website where we can read some advices about the child care food. (Sorry, but I'm not allowed to put any link, so I cannot write the web name. It's the website from "Caring for kids").
For me one of the most important advices is the following one: Most young children like to copy the things that others do. Set an example by eating healthy foods. At home my husband and I always try to prepare healthy food for our son and for us. We usually eat all kind of food: vegetables, soups, fish, eggs, meat, fruits, milk products. We think people have to eat ALL kind of food, it’s to say a balanced food. It’s important that parents do what we say, so it’s essential that parents eat the same food that we give to our children.
