1. Kendamil Organic Infant Formula

9.3/ 10Whole milkMFGMHMOs
Best for: Breastfed babies who are new to the bottle

When a baby is used to the breast, the first bottles of formula can be a hard sell. Kendamil’s first ingredient is organic whole milk, so part of its fat comes from milk itself, including MFGM, a component also found in breast milk. Its GOS contains naturally occurring HMOs. Parents often describe the taste as creamy, which can make switching between breast and bottle smoother.

First ingredientOrganic whole milk
Whey : caseinAbout 60 : 40
PrebioticsGOS with naturally occurring HMOs
Palm oilNone

Pros

  • Creamy taste breastfed babies often accept

Combo feeding usually means a steady, predictable amount of formula each week. Bobbie is a USDA-organic, lactose-based formula on the FDA’s U.S. list, and it’s stocked in our shop, so it’s easy to keep on hand. A Gentle version is available if your baby needs it.

Best for: Families who only give formula now and then

If formula is a backup rather than a daily routine, convenience matters most. NeuroPro comes in single-serve sticks and ready-to-use bottles, so you don’t open a whole tub for one feed. It includes MFGM components, DHA and a 2’-FL HMO.

Best for: Families who prefer a goat milk base

Kabrita is a goat milk infant formula on the FDA’s U.S. list with GOS prebiotics, DHA and ARA. Some parents choose goat milk formulas when they want an alternative to cow milk; ask your pediatrician first if you suspect a milk allergy.

Keep breast milk in the mix with It’s My Leche

Not ranked above because it isn’t a formula. It’s My Leche is 100% human donor breast milk, freeze-dried into sachets. Many combo-feeding families use it on the days when pumped milk runs short.

How we chose formulas for combo feeding

On top of our usual ranking criteria, we looked at three things that matter specifically when you mix breast milk and formula:

  • Acceptance. Formulas with whole milk fat or a creamy taste tend to be easier for breastfed babies to accept.
  • Convenience for partial feeding. Single-serve sticks, sachets and ready-to-use bottles make one-off bottles easier and cut waste.
  • Easy to keep in stock. Subscriptions and in-stock availability matter when you supplement on a schedule.

A simple combo-feeding plan

  • Pick your bottle feeds. Many parents start by replacing one feed a day, like the late-evening bottle, so a partner can help.
  • Protect your supply. If you want to keep breastfeeding, pump around the time your baby has a formula bottle.
  • Go slow. Use a slow-flow nipple and paced bottle feeding so the bottle doesn’t become easier than the breast.
  • Prepare formula exactly as the label says. Never add formula powder to breast milk. See our formula prep guide.

A lactation consultant (IBCLC) can help you build a combo-feeding plan that protects your supply. Most U.S. health plans cover breastfeeding support.

Combo-feeding FAQs

What is the best formula for combo feeding?

Our top pick is Kendamil Organic for its whole milk fat and creamy taste. In our shop, Bobbie Organic and LittleOak goat milk formula are great options, and LittleOak’s travel sachets make occasional bottles easy.

Can I mix breast milk and formula in the same bottle?

You can, as long as the formula is prepared exactly as directed first. Never add powder straight to breast milk. Many parents offer them separately so breast milk isn’t wasted if baby doesn’t finish.

Will supplementing with formula reduce my milk supply?

Milk supply responds to demand, so replacing feeds with formula can lower supply. Pumping when your baby has a formula bottle helps protect it. A lactation consultant can help.

When can I start combo feeding?

Many lactation consultants suggest waiting until breastfeeding is well established, often around 3 to 4 weeks, but every family is different. Talk with your pediatrician if your baby needs supplementing sooner.

Real familiesWe weigh feedback from parents in our community on mixing, tummy tolerance, and availability.
Value & accessWe compare cost per ounce, subscription options, and how easy each formula is to buy in the U.S.
