When you stock your nursery with diapers and wipes, you may want to think about whether you want to get some formula. 

Doctors prefer that moms breastfeed -- and breastfeeding is best. But if you can't breastfeed all the time, or at all, then start by buying just enough formula to last for a week or two. That way, you can see how your baby likes it, before you commit to buying a lot.  

Although formula doesn't contain everything found in breast milk, it has many vitamins and other nutrients that babies need, as well as calories.

Formula From Cow's Milk and Soy

Your baby's doctor should suggest a formula that's right for your little one. Most doctors recommend that babies drink one made from cow's milk. Most formulas available today are made from that. 

If a baby has a milk allergy or the formula doesn't agree with them, doctors may suggest formula made from soy milk.

Other Formulas

If allergies run in your family, your doctor may advise using a “hydrolyzed” formula, which is easier to digest. It may also make it less likely that your baby will get allergies.

Some formulas also have probiotics, the “good” bacteria that live in the gut and are in some yogurts. Probiotics give formula-fed babies the same bacteria that breastfed babies have, to keep their intestines healthier. 

Some formulas have prebiotics, which are carbs that help the good bacteria stay and grow in your baby’s gut. Ask your doctor what your baby needs.

Iron for Baby

Pick a product that’s fortified with iron, unless your doctor says not to. The American Academy of Pediatrics recommends that all babies who aren't breastfed should get formula with iron until they're 1 year old. It helps prevent anemia, which is low iron levels in their blood.

Best Advice for Formula Feeding

Wash your hands first. Just like you would before you prepared anything you were going to eat, you want to have clean hands when you prep your baby's formula.

Use tap water if it’s safe, or bottled water if you’re not sure. You can also use water that you've boiled for at least a minute and cooled. If you're mixing powder or liquid concentrate with water, pay attention to the measurements -- they're important.
