Meat is started somewhere between 9 and 12 months of age.
Your daughter’s doctor recommended the upper age to start meats. The primary concern for starting meat is that it is a good source of iron and iron deficiency anemia is the primary nutritional deficiency in infants and children.
By age one, she should be consuming about 2 servings from the meat, poultry, fish, dry beans and eggs group per day. One serving would consist of about 1 ounce or 1-2 Tbsp. of any of these.
