Babies grow rapidly during their first year, nourished by breast milk or formula. At 6 months of age, they are developmentally ready for solid food, such as an iron-fortified rice cereal, according to the American Academy of Pediatrics. By gradually introducing infants to tasty, wholesome food, parents and caretakers ensure their children get off to a healthy start.
Signs of Readiness
Babies give developmental clues when ready for solid food, according to Bright Futures, an educational division of the American Academy of Pediatrics. Signs of readiness include the ability to control the head and neck, sit without assistance and grasp objects and bring them to the mouth. Infants might have a heartier appetite and a stronger sucking pattern, enabling them to eat a wider variety of food as their digestive system matures. Parents should consult a pediatrician before introducing solid foods.
Introduction
Doctors recommend an iron-fortified, single-grain infant cereal, such as rice cereal, as baby's first food, because it is unlikely to cause a food allergy. With all new solids foods, offer a small amount on a spoon and watch the baby's reaction. Introduce new foods one at a time, observing the baby for any rashes or other reactions that might indicate an allergy. Wait several days before adding a different cereal such as oatmeal or barley.
Other First Foods
Additional first foods include pureed fruits, such as apples, peaches and plums. Vegetables, such as pureed green beans, peas and sweet potatoes, can be introduced early, along with iron-rich meats. Organic and regular varieties of baby food are widely available in grocery stores. Check nutritional labels and follow manufacturer guidelines to make sure the food aligns with your child's age. Making your own baby food also is a viable option that can ensure quality ingredients and save you money.
Considerations
According to Bright Futures, parents should avoid feeding their babies spinach, beets, turnips and collard greens until later in their development. These foods may contain too much nitrate, which can cause methemoglobinemia or blue-baby syndrome. Toddlers are better able to handle these foods, so parents should wait to introduce them until after infancy. Also, resist the urge to add salt, spices or sugar to babies' food, and save cake or cookies for the first birthday party.
Warning
Because of their link to childhood allergies, foods such as eggs, fish, seafood and peanut butter should not be given to young eaters, KidsHealth recommends. Acid from citrus fruit can cause painful diaper rash, and honey may contain spores that can be harmful to infants under 1 year old. Consult with your child's pediatrician for the latest advice on ages to introduce these foods.
