Feeding Your Baby: Your baby’s first food: infant formula

July 2018


Your baby can receive good nutrition from either breastmilk or infant formula. Infant formulas are made from cow’s milk or soy milk. Like breastmilk, they have the right balance of nutrients and energy. Many have added iron, which is necessary for growth. If you use an infant formula, talk with your doctor about which one is best for your baby.

Types of infant formula
• Ready-to-feed is the most expensive. No mixing is necessary and it is ready to use.
• Liquid concentrate formula costs less than ready-to-feed. Mix it with an equal amount of water.
• Powdered formula is the least expensive. Mix one level scoop of powder with 2 ounces of water.

Mixing formula
Always follow label directions when mixing and storing formula. Using the wrong amount of water can cause the baby to become sick or grow slowly. Always wash your hands before mixing formula. Be sure bottles, nipples and caps are washed in hot, soapy water and rinsed in hot, clean water. If you use well water, you may want to boil the water or use bottled water.

Warming bottles
Most babies prefer warm formula. You can heat filled bottles by placing them in a container of warm water for a few minutes. Test the formula temperature on your skin to be sure it is not too
hot. Do not heat bottles in the microwave. The formula may get too hot and burn your baby.

How much formula
The amount of formula your baby drinks depends on individual needs, age and weight. Your baby will be hungrier some days than other days. Use the following chart only as a guide.

Age total amount of formula per day
Birth to 4 months …………………..18 to 32 ounces
4 to 6 months …………………………28 to 45 ounces
6 to 9 months …………………………24 to 32 ounces
9 to 12 months ……………………….24 to 32 ounces

Let your baby decide how much to eat. It is okay if your baby does not finish a bottle. Below are some signs to know when your baby is full:
• Your baby may close their mouth or turn their head away from the bottle.
• Your baby may fuss when you place the nipple on their lips.
• Your baby may play with or bite the nipple.
• Your baby may fall asleep.

You will know your baby is eating enough if:
• They have six or more wet diapers each day.
• They seem happy between feedings.
• Their weight increases steadily.

Remember that regular cow’s milk is not the same as infant formula made from cow’s milk. Babies are not ready for regular cow’s milk until they are 1 year old. After the first birthday, serve whole milk until your baby is 2 years old. After the 2nd birthday, slowly begin serving low-fat milk. Do not put juice or water in the bottle. Solid foods should not be added to your baby’s diet until he or she is 4 to 6 months old.
