Mothers who are unable or choose not to breast feed should select an iron-fortified infant formula. We do not recommend any low-iron formula. Babies should remain on formula until their first birthday. Formula comes in a variety of forms.
Formula types
• Ready-to-use. This formula comes premixed in meal-size bottles or bigger cans. No further preparation is necessary. It is the most convenient form but also the most expensive.
• Concentrate. This formula must be mixed equally with water to turn it into a form suitable for drinking. Once opened the formula can be stored in the refrigerator up to 48 hours. Only mix the amount you expect your baby to eat since the remainder in the bottle must be thrown away after each feeding.
• Powder. This formula must be mixed with water and the directions are on each can. Generally, it is one unpacked level scoop of powder for every two ounces of water. This is usually the least expensive formula. Once the powder is mixed, it can be stored in the refrigerator for 24 hours.
Feeding
As a newborn, your baby will probably begin eating only about one-half to one ounce at a feeding. This will gradually increase. Feeding times will range between every two to three hours initially. This will extend to every four to six hours as your baby grows. We recommend you keep a “flexible” schedule.
