Ready-to-Feed vs Powdered Formula: HiPP and Kendamil Compared

By: The Milky Box Team - Updated October 2026 - 6 Minute Read

Ready-to-feed formula comes as a liquid in a bottle: no scooping, no mixing and no waiting for water to cool. It’s a lifesaver for night feeds, travel and the newborn weeks. But is it the same as powder? We compared HiPP’s and Kendamil’s ready-to-feed formulas with their powders, ingredient by ingredient.

Quick answer:

  • Ready-to-feed is sterile, ready in seconds and needs no water, but costs more per feed and takes up more space.
  • Powder is more economical and lighter to store, but has to be prepared carefully with safe water.
  • HiPP’s ready-to-feed is a slightly different recipe from its powder: it’s made with cream, lists only sunflower and rapeseed oil, has no starch, and has no added probiotic.

Important: never add water to ready-to-feed formula. It’s already at the right strength, and diluting it can be dangerous. Follow the label for storage once a bottle is opened, and throw away any formula left over after a feed.

Ready-to-feed: pros and cons

  • Sterile and ready instantly: no water, no measuring, no waiting. Powdered formula isn’t sterile, which is one reason ready-to-feed is popular in the first weeks.
  • Consistent every time: no risk of scooping too much or too little powder.
  • Great for nights, travel and day care: just open and pour into a clean bottle.
  • But: it costs more per feed, takes up more storage space, and an opened bottle only keeps for a limited time (see the label).

Powder: pros and cons

  • More economical, especially once your baby is drinking larger amounts.
  • Compact and long-lasting: one box or can makes many feeds.
  • But: it needs careful preparation with safe, correctly heated water and accurate measuring.

Many families use both: powder at home and ready-to-feed for nights out and travel. See our guide to preparing formula safely.

Frequently Asked Questions

Is ready-to-feed formula better than powder?

Not nutritionally: both must meet the same infant formula standards. The main differences are convenience, sterility and cost. With HiPP, the recipes also differ slightly (the ready-to-feed has cream, no starch and no added probiotic).

Can I add water to ready-to-feed formula?

No. Ready-to-feed formula is already at the right strength. Never dilute it or mix powder into it.

Do I need to warm ready-to-feed formula?

Many babies drink it at room temperature. If you warm it, stand the bottle in warm water and check the temperature before feeding; don’t use a microwave, as it can heat unevenly.

How long does an opened bottle last?

Follow the storage instructions on the label. Throw away any formula your baby doesn’t finish during a feed.

Can I switch between ready-to-feed and powder?

Many families alternate between the two, for example powder at home and ready-to-feed on the go. Because HiPP’s ready-to-feed and powder recipes differ slightly, watch how your baby gets on and talk to your pediatrician if you’re unsure.
