Daily needs are more or less as follows: at age two, one or two small servings of meat, fish, eggs; three servings of milk, cheese and yoghurt; two or three small servings of fruit and vegetables (including fruit juice); three or four small servings of cereals, pasta, bread and potatoes.

By age 12, your child's needs are smaller than you'd think. Two servings of meat, fish and alternatives; three servings of milk, cheese and yoghurt; four or more servings of fruit and vegetables, six or more servings of cereals, bread and potatoes.
