Reasons to Supplement with Formula
Supplementing your baby’s breast milk diet with formula can sometimes be a hard transition. This is especially true if baby has only ever fed from the breast.
If the baby is very young, nipple confusion can be a challenging side effect of offering a bottle of formula. This could result in a baby who ends up preferring the bottle to breastfeeding, making it harder to switch back to exclusively breastfeeding.
Changing a baby’s diet can come with unforeseen upsets and unknowns, but nevertheless, let’s look at some common reasons why many mothers may need to supplement breastfeeding with formula.
- Your breast milk supply is not meeting your baby’s daily demands.
- Your milk supply hasn’t come in yet.
- Baby is in the nicu.
- Baby is not gaining weight.
- You want to cut down on pumping and or nursing.
- Traveling with breast milk is sometimes too much of a hassle.
- Baby has an intolerance to your breast milk or the dairy you consume while breastfeeding.
- There are medications you need to take that are not compatible with breastfeeding.
- You started your menstrual cycle and your milk supply has not recovered.
As you can see, there are many reasons why you may need to supplement with formula or switch to formula feeding all together.
FAQ’S About Supplementing with Formula
Let’s take a look at some of the most common questions most of us have when it comes to introducing formula for the first time to our baby who has been exclusively fed with breast milk.
What are the Differences Between Breast Milk and Formula?
There are many differences between breast milk and formula. Breast milk is a living organism made from a mother’s blood and contains living cells to perfectly nourish the baby it feeds. Breast milk also protects the baby from illness and disease because of it’s abundance in friendly bacteria and enzymes.
“Breastfeeding provides a protective effect against respiratory illnesses, ear infections, gastrointestinal diseases, and allergies including asthma, eczema and atopic dermatitis.” – American Academy of Pediatrics AAP
Formula is a processed food with a shelf-life, It does not contain any living cells, enzymes or immunity.
Can You Mix Breast Milk with Formula?
The answer is yes, but it is advisable not to do so. Some reasons why it is not recommended to mix breast milk with formula are:
- Wasted breast milk if baby doesn’t finish the bottle.
- Formula doesn’t stay fresh as long as breast milk and should be stored differently.
- Lessens the anti-bacterial benefits of breast milk when consumed on it’s own.
However, there are some things you can to do avoid wasting breast milk if mixing with formula. For one, you can offer breast milk first to avoid wasting left over breast milk if baby refuses the taste of formula.
Two, pause for a short time (10-20 min.) in between feeding breast milk and formula to give baby enough time to regain some hunger and accept the formula.
How to Supplement with Formula without Decreasing Milk Supply
Introducing formula while breastfeeding without decreasing milk supply can be a balancing act. The fear is that your breastfed baby would begin to reject your breast milk after acquiring a preference for formula.
Furthermore, it can be just as hard to get a breastfed baby used to formula and switching them back and forth can be a constant struggle.
To maintain your milk supply while supplementing with formula, it is recommended that you increase or establish a rythmic breast pumping regimen. Consider pumping during every feeding that your baby is receiving formula.
This will keep the supply and demand market consistent.

Infant Formula Preparation
The first and most important step in infant formula preparation is to follow the manufacturers directions for the formula being prepared.
If you feel uneasy or unsure about how to go about preparing your baby’s formula, use a formula dispensing machine like the Baby Brezza, shop for it here at Amazon.
Formula Preparation Guidelines:
- Wash and sanitize your hands before preparing a bottle.
- Clean and sanitize the work space.
- Bottles also need to be clean and sanitized.
- Do not use a microwave to heat prepared formula.
- Use a safe water source.
What Water is Safe to be Mixed with Formula?
You can use any type of clean water, tap or boiled. If you’re using well water and are unsure of the purity of the water source you are using, contact your Local Health Department and speak with your baby’s doctor.
Well water does need regular testing. It is also important to consider the amount of fluoride in the water.
“Regularly mixing powdered or liquid concentrate formula with fluoridated water might increase your child’s risk of developing faint white lines or streaks on the teeth, called fluorosis.” – Mayo Clinic
Purified or distilled water is safe for formula preparation.
Storing and Using Formula
Once mixed, formula has a short life span, unlike breast milk which can be left at room temperature for 4-6 hours and in the fridge 4-5 days.
How Long Does Prepared Formula Last?
- Prepared infant formula lasts two hours.
- Use prepared formula within one hour from when feeding begins.
- Unused and refrigerated formula lasts 24 hours.
Can I Re-feed Any Left-over Formula My Baby Doesn’t Finish?
No, throw out any formula your baby does not finish. The combination of your baby’s saliva and formula can cause harmful bacterial growth.
Best Formulas for Breastfed Babies
Because the American Academy of Pediatrics has determined breast milk is indeed the best source of nutrition for babies up to at least 6 months of age, using a formula closest to breast milk is ideal.
“The American Academy of Pediatrics reaffirms its recommendation of exclusive breastfeeding for about 6 months, followed by continued breastfeeding as complementary foods are introduced, with continuation of breastfeeding for 1 year or longer as mutually desired by mother and infant.” – American Academy of Pediatrics AAP
Formulas Closest to Breast Milk
In order to rank these formulas as to which are closest to breast milk, I looked at the ingredients to see which ones had the fewest synthetic ingredients.
European formulas hold the top spots on the list of being closest to breast milk because of their superiority in quality ingredients and stringent production regulations.
Formulas made in Europe must adhere to a much stricter guidelines than those made for consumption in the U.S.
I also have personal experience with these formulas and can attest to the huge difference in quality one notices right away. My baby had no qualms about drinking it, (like she did the others) and there were no negative side affects either.
I was led to try these European formulas through the recommendation of other moms who were supplementing their babies with it and also had great success.
Take Note: These European formulas are not found on Amazon. I have provided you with links to a trusted online retailer where I purchased mine from and was very happy with the service.

Goat’s Milk Formula Explained
Some of the proteins in cow’s and goat’s milk are the same. Therefore, a baby with a lactose or cow milk intolerance may benefit from goat’s milk. It is also suggested that goat’s milk is more easily digestible.
Goat’s milk is not completely lactose free and not all babies will benefit from goat milk.
You should know that goat’s milk formula is not sold in the Untied States and has not been recognized as a complete source of nutrition for infants.
“EFSA also concluded that there was no convincing data, either in the literature or submitted, to support the belief that the incidence of allergic reactions is lower when feeding goats’ milk based formula compared to cows’ milk based formula. EFSA published its opinion on 12 January 2006, confirming its previous view.” – wholesomebabyfood.momtastic.com
