How to Prepare European Baby Formula: Step-by-Step Guide (HiPP, Holle & Kendamil)

If you've just opened your first box of HiPP, Holle, or Kendamil, you may have noticed something right away: the preparation instructions are printed in German, Dutch, or British English — and they don't always match what American parents are used to. Water temperatures differ between brands, scoop sizes vary, and the feeding tables use milliliters instead of ounces.

The good news is that preparing European baby formula is simple once you understand the basic steps and the one thing that differs most between brands: water temperature. This guide walks you through safe preparation from start to finish, explains the temperature recommendations for HiPP, Holle, and Kendamil, and covers the most common mistakes to avoid.

Why European Formula Preparation Is a Little Different

European formulas follow EU labeling rules, so the box you receive shows instructions in the language of its market — German for HiPP German and Holle, Dutch for HiPP Dutch, and English for Kendamil and HiPP UK. The steps themselves are familiar (boil water, cool, add powder, shake), but three details tend to surprise US parents:

• Water temperature recommendations vary by brand. Some brands ask for noticeably cooler water than others — more on this below.
• Measurements are metric. Feeding tables list water in milliliters (ml). A useful anchor: 30 ml is about 1 fluid ounce.
• Scoops are brand-specific. The scoop in a HiPP box is not the same size as the scoop in a Kendamil tin, so always use the scoop that came with your current package.

Because formulations and instructions can change over time, always treat the printed label on your current box as the final word — this guide explains the general approach, not a replacement for the label. If you're still deciding between powder and pre-mixed options, our ready-to-feed vs powder formula guide breaks down the differences.

Before You Start: What You'll Need

• A clean, sterilized bottle and nipple — see our guide to sterilizing baby bottles safely
• Fresh drinking water (tap water that is safe to drink, or low-mineral bottled water)
• The scoop included in your current formula box or tin
• Clean, freshly washed hands and a clean preparation surface
• The feeding table on your formula's packaging for your baby's age

How to Prepare European Baby Formula: Step by Step

1. Wash your hands and clean the preparation area.
2. Boil fresh water. Bring drinking water to a rolling boil, then let it cool to the temperature your brand recommends (see the temperature table below).
3. Pour about two-thirds of the measured water into the sterilized bottle first. Adding water before powder keeps the ratio accurate.
4. Add the correct number of level scoops for your baby's age using the feeding table on the box. Level each scoop off with a clean knife — don't pack or heap the powder.
5. Close the bottle and shake well until the powder is fully dissolved.
6. Add the remaining water and shake again briefly.
7. Cool to feeding temperature and test. The milk should reach roughly body temperature — about 37°C (98.6°F). Test a few drops on the inside of your wrist before feeding; it should feel warm, not hot.

Feed the bottle promptly after preparation, and discard whatever your baby doesn't finish within about an hour of starting a feed. For exactly how long prepared, opened, and unopened formula keeps, see our complete formula storage guide.

Water Temperature by Brand: HiPP vs Holle vs Kendamil

This is the step where European brands genuinely differ, and it's worth getting right. The table below reflects the general guidance these brands have printed on recent packaging — but instructions can change between production runs, so always confirm against your current box.

Practical takeaway: if you switch brands — say from Kendamil to HiPP — don't carry the old routine over. Re-read the new label, because the water temperature step likely changed. And if you're switching formulas, our formula transition guide covers how to make the change gently.

What About the 70°C (158°F) Guideline?

You may have seen that the World Health Organization and the CDC suggest preparing powdered infant formula with water of at least 70°C (158°F). This guidance is designed to reduce the risk from rare bacteria such as Cronobacter, and it matters most for newborns under 2–3 months, premature babies, and babies with weakened immune systems.

Some European brands (like Kendamil) align with this approach, while others (like HiPP and Holle) recommend cooler water to protect heat-sensitive ingredients such as probiotic cultures. Neither approach is careless — they reflect different regulatory traditions and product designs. If your baby is very young, was born prematurely, or has health concerns, this is a genuinely useful question to bring to your pediatrician; they can help you decide which preparation approach fits your baby's situation.

Getting the Mixing Ratio Right

Most HiPP, Holle, and Kendamil formulas use a ratio of approximately one level scoop of powder per 30 ml (1 fl oz) of water — but always confirm with the feeding table on your box, because scoop sizes and ratios are product-specific.

• Never add extra powder to "make the bottle more filling." Over-concentrated formula is harder on a baby's kidneys and digestion.
• Never dilute with extra water to stretch a box. Diluted formula doesn't provide the nutrition your baby needs.
• Add water first, then powder. Adding powder to an empty bottle and filling with water afterward throws off the ratio.
• Use the scoop from the current box. Scoops differ between brands and even between products from the same brand.

Common Preparation Mistakes to Avoid

• Microwaving bottles. Microwaves heat unevenly and can create hot spots that burn a baby's mouth. Warm bottles in a bowl of warm water or a bottle warmer instead.
• Saving a half-finished bottle for later. Once your baby has drunk from a bottle, bacteria from saliva begin to multiply. Discard leftovers within about an hour.
• Preparing bottles too far in advance. Freshly prepared is best. If you must prepare ahead, follow the storage rules in our formula storage guide.
• Using softened or repeatedly boiled water. Water softeners can raise sodium levels; re-boiling concentrates minerals. Use fresh drinking water each time.
• Guessing at scoops. Estimating "about a scoop and a half" adds up to real ratio errors over a full day of feeds. Level every scoop.
• Ignoring the label after switching brands. As the table above shows, brands differ on the most safety-relevant step — water temperature.

Why Careful Preparation Matters

Correct preparation protects the three things parents choose European formula for in the first place:

• Safety. Proper hygiene, water handling, and prompt feeding minimize bacterial risk — especially important for newborns.
• Nutrition. The nutrient profile printed on the box assumes the exact powder-to-water ratio on the label. Accurate mixing is what delivers it.
• Comfort. Consistent, correctly mixed bottles are gentler on small tummies. Frequent ratio errors can contribute to fussiness or digestive discomfort.

A little routine goes a long way: most parents find that after a week, brand-specific preparation becomes automatic.

Frequently Asked Questions

Do I really need to boil the water first?

Boiling is the standard recommendation on European formula labels — it addresses bacteria both in the water and in the powder (powdered formula is not sterile). This is most important for babies under about 3 months, premature babies, and babies with weakened immune systems. Ask your pediatrician what's appropriate for your baby and your local water supply.

Can I use tap water?

In most US areas, safe drinking tap water that has been boiled and cooled is fine. If you use bottled water, choose a low-mineral (low-sodium) option. Avoid water from softening systems for formula preparation.

Can I prepare bottles in advance for night feeds or daycare?

Freshly prepared is always the first choice. If you need to prepare ahead, cool the bottle quickly and refrigerate it, and use it within the window specified on your formula's label — our storage guide covers the timing rules in detail. For travel days, many parents use ready-to-feed bottles or pre-measured powder in a dispenser.

Can I use a formula maker like the Baby Brezza?

Automatic formula makers are calibrated for specific powders and dispense at fixed temperatures that may not match your brand's label — for example, a machine set to a warm-mix cycle won't meet Kendamil's hotter-water instruction. Check your machine manufacturer's compatibility guidance for your specific formula before relying on it.

Why is my formula foamy or clumpy?

Vigorous shaking introduces air, which creates foam — letting the bottle rest for a minute helps. Clumping usually means the water was cooler than recommended or the powder sat in the bottle before mixing. European whole-milk-based formulas like Kendamil can also foam a bit more than skim-based formulas; this is normal.

Why do HiPP and Kendamil recommend such different water temperatures?

HiPP's cooler range (about 40–50°C) protects the live lactic acid cultures in its Combiotik recipes. Kendamil doesn't use probiotics in the same way and follows UK guidance built around hotter mixing water (at least 70°C). Both are following their own product design and market regulations — the label on your box is always the right instruction for that product. Note that ingredients and instructions can vary by market and change over time, so check your current package.

Final Thoughts

Preparing European baby formula comes down to a handful of habits: clean hands and bottles, freshly boiled water cooled to the temperature on your brand's label, level scoops in the exact ratio from the feeding table, and prompt feeding. The single most important brand difference is water temperature — HiPP and Holle mix cooler to protect sensitive ingredients, while Kendamil follows the hotter UK approach — so whenever you open a new brand or product, take thirty seconds to re-read the label.
