The American Academy of Pediatrics recommends that babies be exclusively breastfed for the first six months of life. A baby's digestive system is immature, and giving solids before a baby is ready can be harmful. Some signs that a baby is ready to start solids include: good head control and the ability to sit up with support; the ability to move food from the front of the mouth to the back; and following the spoon or fork with his or her eyes when you eat.Newborn to Six MonthsUntil they are six months old, babies should be fed breast milk or formula. Adding cereal to a bottle is unsafe and could throw off the balance of a baby's digestive system, causing fussiness and other issues. After four months, if a baby shows signs that he or she is ready to eat solids, talk to your pediatrician about introducing food.Six Months to One YearA baby's first food may consist of baby cereal, such as rice or oat cereal, or a pureed mild fruit or vegetable, such as banana or avocado. The food should be blended with plenty of liquid so it is thin and easy to swallow. Begin by feeding your baby a few teaspoons, and gradually increase the amount given as your baby gets older. Never force your baby to eat, and stop feeding your baby when he or she shows signs of being full. You can continue to add new foods every five to seven days as long as your baby does not show signs of an adverse reaction. You can add texture and finger foods as your baby gets used to eating and begins to develop a pincer grasp, but keep food pieces smaller than a pea. Most pediatricians recommend that you refrain from giving your baby highly allergenic foods like seafood and peanuts until after he or she is a year old.One Year and BeyondAfter children are 12 months old, they can eat most of the same food that you eat. Do not give a child younger than three popcorn, raw carrots, whole grapes or nuts, because these foods may pose a choking hazard. Be creative and let your child sample foods from your plate. Introduce a variety of flavors, colors and textures, and remember to give your child plenty of fruits and vegetables, whole grains and healthy fats.There is no need to rush when introducing solids to babies. During the first year of life, solids simply give children the chance to explore tastes and textures. Giving children a variety of healthy foods and having them join you for meals can help them develop healthy eating habits for life.
