foods, appropriate types of foods to feed an infant, and hygiene practices are effective at improving these feeding practices. Nutritional needs and the amount of food Newborns need a diet of breastmilk or infant formula. About 40% of the food energy in these milks comes from carbohydrates, mostly from a simple sugar called lactose. As shown in the 2008 Feeding Infants and Toddlers study, the overall diet of babies and toddlers, the primary consumers of baby food, generally meets or significantly exceeds the recommended amount of macronutrients. Toddlers and preschoolers generally ate too little dietary fiber, and preschoolers generally ate too much saturated fat, although the overall fat intake was lower than recommended. Micronutrient levels were typically within the recommended levels. A small group of older infants in the American study needed more iron and zinc, such as from iron-fortified baby foods. A substantial proportion of toddlers and preschoolers exceeded the upper recommended level of synthetic folate, preformed vitamin A, zinc, and sodium (salt). The World Health Organization recommends starting in small amounts that gradually increase as the child gets older: 2 to 3 meals per day for infants 6 to 8 months of age and 3 to 4 meals per day for infants 9 to 23 months of age, with 1 or 2 additional snacks as required. Preparation and feeding Baby foods are either a soft, liquid paste or an easily chewed food since babies lack developed muscles and teeth to effectively chew. Babies typically move to consuming baby food once nursing or formula is not sufficient for the child's appetite. Babies do not need to have teeth to transition to eating solid foods. Teeth, however, normally do begin to show up at this age. Care should be taken with certain foods that pose a choking hazard, such as undercooked vegetables, grapes, or food that may contain bones. Babies begin eating liquid style baby food consisting of pureed vegetables and fruits, sometimes mixed with rice cereal and formula, or breastmilk. Then, as the baby is better able to chew, small, soft pieces or lumps may be included. Care should be taken, as babies with teeth have the ability to break off pieces of food but they do not possess the back molars to grind, so food can be carefully mashed or prechewed, or broken into manageable pieces for their baby. Around 6 months of age, babies may begin to
