How much protein should I give my baby?

Proteins should account for 10% to 20% of the calories consumed each day. Protein is essential to the structure of red blood cells, for the proper functioning of antibodies resisting infection, for the regulation of enzymes and hormones, for growth, and for the repair of body tissue. Meat, milk, cheese, and egg are complete proteins that have all the essential amino acids. Other sources of protein include whole grains, rice, corn, beans, legumes, oatmeal and peas.
