Don't add cereal to the bottle. If your baby can't take cereal on a spoon she is not ready for it. Solid foods do not affect the length of time your baby sleeps. Digestive system has matured. There is a lower risk of allergies.
Stomach is larger so there is less chance of overfeeding.
A variety of foods so your baby can learn to enjoy many different tastes. Babies may even like foods you don't. Plain vegetables, fruits and meats without added salt or sugar. Single foods are recommended rather than mixtures. Babies do not need custards and desserts.
