Choose a formula

Although breast milk is the best source of nutrition for your baby, you shouldn’t feel bad if you are unable or choose not to breast feed. Baby formulas are specially made to meet babies’ nutritional needs

Changing Formula

Sometimes it may be necessary to change the kind of formula that your baby drinks. Extreme fussiness, certain food allergies, or a need for more iron are some of the reasons why your baby’s formula may need to be changed.

If you’re concerned about your baby’s stool habits or about the color or consistency of the stool, changing his or her formula isn’t necessarily the answer. How often babies soil their diapers and the color and consistency of their stool is different from baby to baby. Talk with your doctor before changing your baby’s formula–you may not need to after all.

Mixing formula

The most important thing to know is that you must follow the directions on the formula container exactly. Always measure carefully and never add extra water to the formula.

If you are using concentrated liquid or powder, use cold (not warm) tap water to make formula. Run the cold water at least 2 minutes to clear stale water out of the pipes. If you use well water or there are problems with the water in your town, you may want to boil the water first or use bottled water. If you boil the water, let it cool off before mixing it with the formula. Always use a clean cup to measure the water.

Warming bottles

You can probably feed your baby a bottle without warming it first. If your baby seems to prefer warm formula, you can put the filled bottle in a container of warm water and let it stand for a few minutes. Check the temperature of the formula on your skin before feeding it to your baby, to be sure it isn’t too hot. The formula should only be lukewarm–not very warm at all.

Don’t heat bottles in the microwave. Microwaves heat foods and liquids unevenly, and this can cause hot spots in the formula that can burn your baby. - Pregnancy, Baby & Parenting information
