Video Review: Which GROWNSY Bottle Warmer is Right for You?

In those first few weeks with your baby, it can feel like most of your day revolves around feeding. Whether you're breastfeeding, formula feeding or combo feeding, there’s one thing that becomes very clear, very fast: babies don’t like to wait when they’re hungry. 

Once you add bottle feeding and bottle prep to the mix, mealtime can be delayed even more. Some new parents turn to bottle warmers to cut time out of the feeding process, but choosing the right one can feel like a task since there are lots of new, high-tech options to choose from. To help you decide, we tapped Babylist mom Julie to try three of GROWNSY’s best-selling bottle warmers (they’re super popular on Amazon). Watch the video above to see just how they work, and below, learn more about each one before deciding which one deserves a spot on your Babylist registry. 

What are bottle warmers good for?

Many parents end up introducing bottles at some point—maybe it’s for night feeds, sharing the load with a partner or preparing for daycare. And while you don’t need one, a good bottle warmer can become an unsung hero of your feeding setup (hello, blurry-eyed 3 A.M. feeds).

Technically, yes, you can warm a bottle under hot water or in a bowl. But that method takes time (which you probably don’t have) and risks overheating or warming unevenly, which can break down nutrients, especially in breast milk. Here are some of the main reasons parents swear by using a bottle warmer: 

• Warms bottles quickly: Get bottles ready fast without guessing how long is too long.

• Protects breast milk nutrients: Bottle warmers warm gently without overheating.

• Offers consistent, reliable quality: Get to a safe warmth every time; no more testing the temp on your wrist.

• Support for sleepy nights: They’re easy to use—just press a button and wait for the beep.

What’s special about GROWNSY bottle warmers?

If you’ve searched for baby gear on Amazon or read parent reviews online, chances are you’ve seen GROWNSY. Their bottle warmers consistently rank high for performance and value, with thousands of glowing reviews from new parents and gift-givers alike.

When it comes to their bottle warmers, all GROWNSY models share the same core benefits:

• Warm bottles evenly without hot spots

• Support multiple bottle types (plastic, glass, silicone, breast milk bags)

• Include sterilization features

• Are BPA and BPS free

• Use easy controls and clear LED displays

But each model offers unique perks, so choosing the right one really comes down to your lifestyle and preferences.

Comparing GROWNSY bottle warmers

Here’s a quick look at the three most popular GROWNSY models—the Nutri 10‑in‑1 with Auto‑Lift, the Single 8‑in‑1 and the Double 8‑in‑1—along with a breakdown of what sets them apart.

GROWNSY Bottle Warmers Comparison Guide

Model	Stand out Features	Performance Snapshot	Who It’s Best For
Nutri 10-in-1 with Auto-Lift	Auto-lift basket pops up the bottle when it reaches temp; has a nightlight and memory function so it remembers your preferred settings.	Warms ~4 oz in under 3 minutes. Includes beep to alert when warming’s done; screen with countdown.	Night-feed warriors; parents who want a mostly hands-free experience when the house is dark or quiet.
Single 8-in-1	Streamlined version: same core warming, defrosting, food heating; bright countdown display; domed lid for sterilizing bottles or pacifiers. Fewer buttons, simpler interface.	Under 3.5 minutes to warm 4 oz; LED timer; intuitive controls.	Single-feed families, small kitchens, folks who want something reliable without extras.
Double 8-in-1	Same feature set as the Single 8-in-1 (minus auto-lift and nightlight), but can warm two bottles at once.	Depending on bottle material (plastic/glass/silicone), warming 4 oz takes ~3-7 minutes per bottle—but you’re doing two at once; all the usual modes + sterilizer; countdown timer and beeps.	Twins, tandem feeding, or very busy schedules where two bottles often need warming back-to-back

The Nutri 10-in-1 with Auto-Lift

This is the “smart” warmer. Once the bottle is ready, the warming basket lifts it up so it’s easier (and safer) to grab—no more dunking your hand into hot water.

• Auto-lift feature raises the bottle when done

• Nightlight helps during dark nursery runs

• Memory function remembers your warming preferences

• Fast warm time warms 4 oz of milk or formula in under 3 minutes

• Smart details like a touchscreen with countdown timer

This one’s a win for parents doing a lot of middle-of-the-night feeds who want a little more ease—and light—without waking up the whole house.

The 8-in-1 Single Bottle Warmer

This streamlined version offers the same core functions—fast warming, food heating, sterilization—but without the extras like auto-lift or nightlight.

• Simple touchscreen with fewer buttons

• Bright LED timer for countdown visibility

• Slightly smaller footprint (great for compact kitchens)

• Still warms 4 oz in under 3.5 minutes

If you’re mostly warming one bottle at a time and don’t need all the bells and whistles, this one gets the job done, and fast.

The 8-in-1 Double Bottle Warmer

Feeding two babies? Or just dealing with round two before you’ve cleaned up from round one? This model warms two bottles at once, and still includes the sterilizer, defrost and baby food heating features.

• Fits two bottles side by side

• Takes 3–7 minutes depending on bottle type (plastic, glass, silicone)

• Beeps when warming begins and ends

• Countdown timer keeps you updated

It’s a bigger appliance, but if you’ve got twins or you’re warming bottles in quick succession, the time you save might be worth the space.

Who do we recommend GROWNSY bottle warmers for?

If your feeding routine could use a little more ease (especially in the middle of the night), GROWNSY has a model that can help. The Nutri is great for low-light, hands-off feeding thanks to its auto-lift and nightlight; the Single 8-in-1 is a no-fuss, space-saving option for one-bottle-at-a-time families; and the Double 8-in-1 is a game changer for twins or back-to-back bottles. 

Since all three come in at an accessible price point (each one is under $50), you also get premium features without the premium price tag. Whatever your setup, GROWNSY’s warmers combine safety, speed and simplicity, so you can spend less time warming bottles and more time snuggling your baby.
