How To Transition From Breastmilk to Formula

Breast milk is known for its numerous health benefits, including minerals, vitamins, and immune cells. These nutrients help babies adjust to their new environment and grow strong and healthy. As a result, learning how to transition from breastmilk to formula is a core part of every child’s development.

Breast milk provides all the necessary ingredients for growth and development, such as proteins, fats, carbs, vitamins, and minerals. It also has antibodies and immune factors to protect babies from infections and illnesses. Breastfeeding offers numerous motherly benefits, such as postpartum weight loss and reduced cancer risk

The Most Important Reasons to Switch from Breast Milk to Formula

Many reasons a parent might choose to switch from breast milk to formula. Some common reasons include the following:

  • Insufficient milk supply: Some mothers cannot produce enough breast milk to meet their baby’s needs, making formula supplementation necessary.
  • Going back to work: Many working mothers find it challenging to continue breastfeeding after returning to work and choose to switch to formula.
  • Medical reasons: Certain medical conditions, such as breast surgery or a chronic illness, may make breastfeeding difficult or impossible.

Regardless of the reason, switching from breast milk to formula is a personal decision that should be made in consultation with your baby’s pediatrician.

What to know about formulas before transiting 

When transitioning from breastmilk to formula, selecting a formula that is age and nutritionally appropriate for your baby is critical. There are four main types of formulas: 

  • Cow’s milk-based formula: is the most commonly used and is made from cow’s milk proteins with added lactose or other sugars and oils. Some milk-based formulas are specially processed to make them easier for babies to digest. This formula provides all the essential nutrients for a baby’s early stages of development and is well-tolerated by most babies.
  • Soy-based formula: uses soy protein instead of cow’s milk protein and replaces lactose with sucrose or glucose. According to the American Academy of Pediatrics (AAP), there is no advantage to choosing soy-based formula over cow’s milk-based formula, except in rare cases where a baby has galactosemia. In such cases, a doctor may recommend a hydrolyzed formula. According to the AAP, there is no evidence that soy-based formula helps with colic or fussiness.
  • Hypoallergenic formulas: are cow’s milk-based but feature proteins broken down into smaller proteins through hydrolysis. This makes the proteins unrecognizable to the body as cow’s milk, making them suitable for babies with milk protein allergies that cause skin rashes or wheezing. 
  • Specialized formulas: are for infants born premature or with specific conditions, such as heart disease, malabsorption syndromes, or difficulties digesting fat or processing certain amino acids. These formulas are tailored to meet the unique nutritional needs of these infants.

Types of weaning 

It’s important to note that every mother and baby is different, and the best method of weaning will vary based on individual circumstances and preferences. The three significant types of weaning.

  1. Gradual weaning: This method slowly reduces the frequency and amount of breastfeeding. It allows the mother’s body to adjust to the decrease in demand for milk production, which can minimize discomfort and engorgement.
  2. Cold turkey weaning: This method abruptly stops breastfeeding, often due to a specific event or need, such as returning to work or the baby refusing to breastfeed. While this method can be effective, it can also result in more discomfort for the mother due to engorgement and a sudden decrease in milk production.
  3. Combination weaning: This method involves a combination of gradual and cold turkey weaning, where the mother may gradually reduce breastfeeding frequency while supplementing with formula or solid foods. 

Suggestions for a Smooth Transition

Here are some steps you can follow to make the transition from breastmilk to formula as smooth as possible:

Consult a pediatrician

Before making the switch, you must consult a pediatrician to determine the best formula for your baby. Your pediatrician can help you choose the right formula based on your baby’s age, health, and nutritional needs.

Gradually introduce formula

If your baby is used to breastfeeding, a sudden switch to formula can shock their system. To avoid any upset, try to gradually introduce formula into their diet by slowly replacing one feeding formula daily. This gradual transition will give your baby time to adjust and prevent digestive issues.

Use a slow-flow bottle

To prevent overfeeding and reduce the risk of nipple confusion, it is critical to utilize a slow-flow bottle when switching from breastfeeding to formula. The slow-flow bottle will aid in controlling the flow of the formula and preventing your baby from choking.

Follow the instructions on the formula label

It is essential to follow them closely to ensure that your baby gets the proper nutrition. Overfeeding or underfeeding your baby can lead to health problems and affect their growth and development. Make sure to measure the formula accurately and prepare it as directed.

Be patient

Transitioning from breastmilk to formula can be difficult for both baby and parent. Be patient and give your baby time to adjust to the change. Some babies may take a few days to get used to the new taste and texture, while others may take a little longer. If your baby seems uncomfortable or fussy, try offering the bottle in a different position or warming it to a different temperature.

Practice Proper Hygiene

In addition to all we’ve listed above, it is also important to practice proper hygiene with bottle usage. Remember to wash your baby’s bottle after each use with soap and warm water. This way, you’d be protecting your little one from infections that lead to sicknesses during the transition.

Consider breastfeeding support

If you are still breastfeeding and switching to formula, consider breastfeeding support. Several resources are available to help you with the transition. These include lactation consultants, breastfeeding support groups, and online resources. Also, talking to other mothers who have gone through the same experience can be especially helpful.

Caring for Yourself During the Weaning Process

Weaning is not just about your baby, it’s also about taking care of yourself.

Even if your baby adapts well to formula, paying attention to your health as you gradually reduce breastfeeding is essential. Sudden cessation of breastfeeding can lead to health problems for mothers, so approach weaning safely.

Also, it helps to note that breastfeeding and formula feeding can be combined if it is possible and convenient for you.


While transitioning from breastmilk to formula can be challenging, it is essential to remember that formula can provide your baby with the nutrition they need to grow and thrive. Additionally, it can provide a sense of independence and freedom for mothers who are unable to breastfeed.
