If you add too much water, your baby will not get enough food to grow. Powder - you add water and shake or stir it to mix. This is the least expensive type of formula. Special formulas - if your baby isn't growing well or is allergic to her formula, your doctor may want her changed to a special formula, like one made from soy. Schedule for feeding You should feed your baby whenever she is hungry.
Most babies eat every two to four hours.
Do not wait longer than six hours between feedings. Your baby's stomach is small and will only hold one to three ounces at first. Large babies may need to eat more often and take more at each feeding. Bottle feeding usually takes 20-30 minutes. When your baby is full, she will stop sucking and swallowing.
