Can You Mix Formula and Breastmilk? A Comprehensive Guide for New Parents

Whether you’re exclusively breastfeeding, exclusively formula feeding, or considering a combination of both, we’re here to support you on your parenting journey.

Is Combining Breast Milk and Formula Safe?

The Short Answer: Yes, mixing formula and breast milk is generally safe. There's a common misconception that combining the two can be harmful, but this isn't true. Many parents successfully combine these to meet their baby’s nutritional needs. 

Understanding Breastmilk and Formula

Breast milk is often hailed as the ideal food for infants. It’s packed with essential nutrients, antibodies, and live enzymes that support optimal growth and development. Breast milk changes its composition over time to meet your baby's evolving needs. Exclusive breastfeeding is recommended for the first six months of life, and continuing to breastfeed alongside solid foods is beneficial for up to a year or longer. However, the reality is that some parents choose not to breastfeed or are unable to breastfeed for a variety of reasons. That’s where formula comes in.

Formula is a carefully formulated alternative designed to mimic the nutritional content of breast milk. While it doesn't offer the same immunological benefits, it provides essential proteins, carbohydrates, fats, vitamins, and minerals for your baby's growth. Baby formula is a great substitute when breastfeeding or maintaining breast milk supply is not an option.

While infant formula strives to replicate breast milk, there are inherent differences. Breastmilk contains a complex array of components, including antibodies, live enzymes, and hormones, that are difficult to fully replicate in a formula. However, both breast milk and formula provide the foundational nutrients necessary for a baby's healthy development.

At Serenity Kids, our toddler formula is made with A2 milk protein, a gentle alternative to the more common A1 protein. Research suggests that A2 milk may be easier on a baby's digestive system.

Reasons For Mixing Breast Milk and Formula

Many families choose to combine formula and breast milk for a variety of practical and personal reasons. Whether you’re pumping regularly, navigating changes in your supply, or simply finding a feeding rhythm that fits your lifestyle, mixing human milk with formula can offer the flexibility you need. Below are some of the most common reasons parents mix breast milk and formula:

Low Milk Supply

It’s common for some moms to experience low milk supply, and that’s okay! Our very own Serenity had low milk supply, which was the inspiration for creating Serenity Kids formula. Mixing breast milk with formula can help ensure your baby is getting all the nutrition they need without any stress.

Returning to Work or School

Balancing work or school with a new baby is a lot to handle. Mixing breast milk with formula can offer the flexibility you need to keep your baby well-fed while managing your busy schedule.

Baby's Weight Gain

If your baby is not gaining weight as expected, supplementing with formula can be a helpful way to ensure they’re getting enough calories and nutrients. Every baby grows at their own pace, but a little extra nutrition can make a big difference in some cases when a baby isn’t following their growth curve

Baby's Preference

Some babies may develop a preference for a certain taste or texture. Mixing breast milk with formula can make the transition smoother if your baby seems to enjoy formula or if they’re not getting enough satisfaction from breast milk alone.

Medical Reasons

Certain medical conditions in either the mother or baby might make breastfeeding alone challenging. In such cases, supplementing with formula can help maintain your baby’s health and well-being without compromising on necessary nutrients.

Transitioning to Formula

If you’re planning to switch to formula entirely, mixing it with breast milk can make the transition easier for your baby. It allows them to get used to the new taste and feeding routine gradually.

Consulting with a Healthcare Professional

Before making any changes, it’s important to talk with your healthcare professional. They can provide personalized advice and support, ensuring that both you and your baby are happy and healthy with the feeding choices you make.

Remember, every family's journey is unique. Whether you’re exclusively breastfeeding, formula-feeding, or doing a mixture of both, you’re doing an amazing job providing for your baby.

How to Mix Formula and Breastmilk

To safely combine formula and expressed breast milk:

1. Prepare the formula: Follow the instructions on the can of formula carefully.

2. Combine with breastmilk: Once the formula has cooled to body temperature, you can add breastmilk to the bottle.

3. Temperature: Ensure the combined mixture is at a comfortable feeding temperature.

Important: Never use breastmilk instead of water when preparing formula. This can lead to an imbalance of nutrients.

How to Store Mixed Formula and Breast Milk

Proper storage is essential to keep your baby safe, especially when you’re combining breast milk and formula for combination feeding. Whether you prepare bottles ahead of time, mix after pumping, or keep expressed milk ready for bottle feeding later in the day, following safe storage steps ensures your feeding baby routine stays smooth.

1. Refrigerate promptly

After you combine breast milk with prepared formula, place the bottle in the refrigerator immediately. Mixed milk should be used within 24 hours to maintain safety and nutrient quality.

2. Follow safe warming practices

When it’s time to feed, warm the bottle gently in a bowl of warm water. Avoid microwaving, as it can create hot spots and damage beneficial lactation nutrients in the breast milk.

3. Discard leftover milk after feeding

Once your baby has started bottle feeding, any remaining mixed milk should be discarded within one hour. This helps prevent bacterial growth and keeps feeding safe for your baby.

Potential Challenges and Considerations

While mixing formula and breastmilk is generally safe, it's essential to be aware of potential challenges:

• Nipple confusion: Some babies might experience difficulty latching due to the different flow rates between breast and bottle. This is typically temporary and may just require trying a few different bottles or nipples.

• Changes in feeding patterns: Your baby's feeding habits might change as you introduce formula.

• Shelf life: A bottle containing both breastmilk and formula has a shorter shelf life than breastmilk alone.

To help with a smooth transition, consider starting with small amounts of formula and gradually increasing it as needed. Also, consult with your health care provider for personalized guidance.

Benefits of Combining Breastmilk and Formula

Combining breastmilk and formula can offer some advantages for both mother and baby.

• Nutritional Balance: By combining the two, you can provide your baby with a well-rounded nutritional profile. Breastmilk offers essential antibodies and nutrients, while formula complements these with specific vitamins and minerals.

• Supporting Breastfeeding Goals: Supplementing with formula can help maintain your milk supply, especially if you're returning to work or school. It can also alleviate some of the pressure to exclusively breastfeed, reducing stress and promoting bonding.

• Easing the Transition: Whether you're transitioning to formula or back to breastfeeding, gradually introducing the other milk can help your baby adjust more smoothly. It can also prevent abrupt changes in your baby's feeding routine.

Tips for Successful Combination Feeding

• Building a Feeding Schedule: Creating a feeding schedule that works for both you and your baby is essential. Consider factors like your work schedule, baby's hunger cues, and desired breastfeeding frequency.

• Storing and Handling Breastmilk and Formula: Proper storage is crucial to maintain the quality of both breastmilk and formula. Adhere to the recommended storage guidelines for each.

• Involving Partners and Caregivers: Ensuring everyone involved in your baby's care understands the feeding plan is important. This helps maintain consistency and reduces confusion.

• How to Monitor Your Baby’s Response: Keep a close eye on your baby's behavior after introducing formula. Look for any signs of discomfort, such as fussiness, gas, or changes in bowel movements. If you notice any adverse reactions, consult your healthcare provider.

Remember, every baby is different, and what works for one may not work for another. Be patient, flexible, and trust your instincts as you navigate combination feeding.

Toddler Formula and the Benefits of A2 Milk

As your child grows into a toddler, their nutritional needs evolve. Toddler formula is designed to support their continued development with a blend of essential nutrients tailored to their growing bodies. Serenity Kids offers a toddler formula that provides a complete and balanced diet. Understanding when babies stop drinking formula can help you feel confident about what to expect as your baby grows.

One key ingredient in our toddler powdered formula is A2 milk, which may be easier on digestion compared to other types, as differentiated in our blog on A1 vs. A2 Milk. Unlike traditional cow's milk, which often contains a mix of A1 and A2 proteins, our toddler formula exclusively uses A2 milk . Research suggests that A2 milk may be easier to digest for some individuals. While more research is needed, many parents report that their children experience improved digestion when consuming A2 milk-based products.

By choosing Serenity Kids toddler formula, you're providing your child with a nutritious foundation for their growing years.

Takeaway

What to feed your baby is an important decision as a parent. Whether you choose to breastfeed exclusively, formula feed exclusively, or combine the two, your goal is to provide your baby with the solid nutrition to support their rapid growth and development.

Mixing formula and breastmilk can be a great option for many families. It offers flexibility, ensures your baby is well-nourished, and can help with the transition between the two. Remember, every baby is unique, so what works for one family might not work for another.
