How to introduce a bottle
Most Moms find formula feeding easy—but introducing a bottle may take some trial and error. Here are 5 ways to make it easier:
  • Make it gradual. Start by giving one bottle a day and gradually build up. Another way to supplement is to let your baby nurse first and then finish off with formula.

  • Time it right. Try offering a bottle when your baby is hungry but not famished, so he’s less likely to fuss. In most cases, the optimal time to start supplementing is after the first month so your milk supply is well-established.

  • Let Dad or Grandma offer the first bottle. This can work better because your baby may associate you with strictly breast milk at first.

  • Start out with breast milk in the bottle. This cuts down on the number of new experiences baby has all at once. Plus, the familiar taste may help him to accept the bottle faster—and once he befriends it, adding formula won’t seem like a big deal.
  • Use a bottle nipple that resembles your baby’s pacifier. Putting some breast milk on the nipple is another way to encourage him to accept the bottle. Once he tastes the breast milk, he may start sucking to get more.
Become a mix master Making formula isn’t hard. Just follow the directions on the label, consider these important tips, and in no time you’ll be an expert.

But remember—accuracy matters. Too much or too little water and your baby won’t get the right mix of nutrients.
Bottle basics every Mom needs
  • Follow label directions carefully
  • Always use formula before the expiry date
  • Wash your hands and your work area
  • Boil clean bottles, nipples, caps and utensils in water for 2 minutes
  • For healthy term babies less than 4 months old, boil the water you use to make formula for 2 minutes
  • If you need to warm bottles, put them in a pot of hot (but not boiling) water but don’t submerge the nipple
  • NEVER microwave a bottle—you could seriously burn your baby
  • If there’s any formula left in a bottle, throw it out within 1 hour of starting the feeding
Storing prepared formula Prepared bottles of formula (from liquid, concentrate or powder) should be refrigerated and used according to the table.

If you plan to introduce formula, either as a supplement to breast milk or exclusively, you’re not alone. Recent consumer studies show that 9 out of 10 new mothers use formula at some point during their baby’s first year. They do it for many reasons, including to supplement breastfeeding, to share feeding duties and to make the transition back to work.

When it comes to breast-feeding vs. formula-feeding, don't get hung up on that middle word versus. There's a third option that can work surprisingly well: feeding your baby breast milk and formula. This combination feeding, or supplementing approach is more common than you might realize.
Concerned about nutrition? Thanks to decades of research and scientific advancements, today’s infant formulas are closer to breast milk than ever before and contain the nutrients your baby needs to grow and thrive.
"I used Enfamil A+ for my first child when my breast milk stopped producing. It was a saving grace. I now have a second child who just turned a month old and is on the same formula. I absolutely love the formula."
