Step-by-Step Guide: How to Switch from Breastmilk to Formula

Posted by Formuland on

Introducing formula to a breastfed baby can be a challenging but important decision for many parents. With this step-by-step guide, you will learn how to transition from breastmilk to formula feeding successfully.

Choosing the Right Formula

Choosing the right formula is crucial for your baby's nutritional needs. Consider factors such as age, dietary needs, and allergies.

European infant formulas, such as HiPP, Holle, Aptamil, Lebenswert, and Kabrita, are often preferred for their high-quality ingredients.

Proper supplementation or alternative formulas are necessary for infants who cannot consume cow's milk-based formula due to allergies or intolerances. Goat milk formulas and hypoallergenic formulas are alternatives for infants with specific dietary requirements or allergies.

Best Time To Transition From Breastmilk to Formula

The best time to transition from breastfeeding to formula feeding is a decision that should be made in consultation with a healthcare professional. The World Health Organization (WHO) and the American Academy of Pediatrics (AAP) recommend exclusive breastfeeding for the first 6 months, followed by partial breastfeeding up to 2 years.

The Best Strategy: How to Switch from Breastmilk to Formula

Introduce the Formula Slowly

To transition from breastmilk to formula successfully, it’s important to do so gradually. Here are two ways you can try:

  • Mixing:  You can begin by mixing formula with breastmilk in a ratio of 25% formula and 75% breastmilk. As the days or weeks progress, steadily increase the amount of formula while decreasing the amount of breastmilk in the mixture. 

    • Breastmilk then Formula: According to La Leche League International, it's best to give breastmilk and formula separately instead of mixing them. This way, you can avoid wasting breastmilk if your baby doesn't finish the bottle. By offering breastmilk first and on its own, you make sure that your baby receives all the benefits of breastmilk.

    This gradual approach allows your baby's digestive system to adjust to the new formula, ensuring a smooth transition from breast milk to formula feeding.

    Starting with the Bottle

    Introducing a bottle feeding in place of one breastfeeding session can be helpful in easing the transition from breastmilk to formula. 

    It’s recommended to select a feeding time when your baby is least interested in breastfeeding, such as during the afternoon with the feeding before bedtime as the last to go. This timing allows your baby to become more familiar with the bottle and reduces resistance to the new feeding method. 

    By gradually replacing one breastfeeding session with a bottle feeding, your baby can begin to adjust to the new feeding method without feeling overwhelmed or stressed.

    Tricks to Encourage Formula Feeding

    • Enlist Help: When your baby’s learning how to transition from breastmilk to formula, enlisting the help of a family member or friend to administer the first bottle of formula can be beneficial. Babies are sensitive to their mother's scent, and having another caregiver introduce the bottle helps reduce confusion and eases the transition process.

    • Slow-Flow Nipples: It’s also important to choose bottles equipped with slow-flow nipples that mimic the natural flow of breastmilk. This similarity in flow makes it easier for babies to adapt to bottle feeding, as they need to exert effort to extract the formula, similar to breastfeeding.

    • Encourage Initial Latching: Before feeding formula, consider placing a small amount of breastmilk on the bottle's nipple to encourage initial latching and help your baby become more accustomed to the new feeding method.

    • Side Dish: For babies resistant to bottle feeding, consider incorporating formula into their solid foods. Wait until your baby is between four to six months old and gradually introduce small amounts of formula into their cereal or pureed foods. This helps familiarize your baby with the taste of formula before transitioning to bottle feeding.

    • Use a Bottle Warmer: A bottle warmer ensures that the formula is heated to the appropriate temperature for your baby, replicating the natural warmth of breastmilk. It provides a convenient and consistent way to warm bottles quickly, saving time and effort compared to other methods like running the bottle under warm water or using a microwave.

    By incorporating these strategies, you can support a smooth transition for your baby from breastmilk to formula feeding.
