Cooling Relief
9.0/10The gel-filled keys provide immediate cooling when placed in the fridge for 30 minutes. Parents consistently report that this quickly soothes swollen gums, making the teething phase more bearable for both baby and caregiver. One Wirecutter editor noted that cooling teethers are a top pick for newborns, and the Nuby delivers that relief at a fraction of the price of Sophie the Giraffe.
Buy if your baby responds well to cold; skip if they prefer room-temperature textures.
Value for Money
9.5/10At under $5, the Nuby IcyBite Keys are one of the most cost-effective teethers on the market. With over 110,000 reviews, it's clear that parents see this as a low-risk purchase that often becomes a go-to. Compared to the $25 Sophie the Giraffe, the Nuby offers similar cooling relief for a fifth of the price, making it an ideal starter teether. In a category where some teethers cost $15 or more, the Nuby is a steal that performs well.
For budget-conscious families, this is a no-brainer add to the baby registry.
Build Quality and Durability
7.0/10The plastic keys are sturdy yet lightweight, but the gel filling poses a leakage risk if chewed aggressively. Several reviews mention that a determined baby can puncture the key, releasing the gel. This isn't harmful but creates a mess. It's best to discard at the first sign of wear and have a backup on hand. We recommend inspecting the keys before each use for signs of damage, as with any gel-filled teether.
Monitor use and replace if teeth marks deepen; keep a spare for peace of mind.
Ease of Use
8.5/10The key ring shape is perfectly sized for small hands, and the fridge prep is effortless. Parents just toss the keys in the refrigerator door and they're ready whenever baby needs them. Cleaning requires hand washing, which is a minor inconvenience, but the simple design means there are no hard-to-reach crevices. While hand washing is simple, a quick rinse under warm water is all that's needed daily.
Great on-the-go option; toss in a sanitizer bag if you need to clean while out.
Features and Textures
6.5/10The Nuby lacks the textural variety that helps older babies work through all stages of teething. While the smooth keys are perfect for initial gum pain, babies soon need bumps, ridges, and varied surfaces to massage different areas. Teethers like the RaZberry's BerryBumps or the Manhattan Toy Winkel's loops provide more chewing options. But for the 3-6 month window, the smooth design is actually a benefit for delicate gums.
For early teethers (3-6 months), this is sufficient; transition to a textured teether after that.
What Users Say
4.7★ · 110,934 Amazon reviewsAmazon Buyers
4.7★ · 110,934 reviewsWith a 4.7-star average from over 110,000 ratings, Amazon buyers overwhelmingly praise these teething keys for their effective cooling and easy grip. Many parents note that placing them in the fridge provides immediate gum relief, and babies as young as three months can hold them. A small minority mention that the keys can leak gel if chewed too vigorously, but most agree this is a reliable, budget-friendly choice.
YouTube Reviewers
In video reviews, lactation consultant Mama Nurse Tina and childbirth educator Bridget Teyler stress the importance of safe, non-toxic materials and proper oral development. While their advice focuses on pacifiers, the same principles apply to teethers: BPA-free silicone and round, ergonomic shapes support healthy oral function. The Nuby IcyBite Keys’ rounded key-ring design and safe materials align with these expert recommendations, providing gentle gum stimulation without harming delicate mouths. Both professionals affirmed that the Nuby's BPA-free construction and ergonomic shape are baby-safe.
Expert Publications
Wirecutter's infant gift guide, written by parents with 35 years of combined experience, named Sophie the Giraffe as the best teething toy for its rubber texture and keepsake quality. While Sophie costs around $25, the Nuby IcyBite Keys fill the same soothing role for under $5, with the added benefit of gel cooling. The Wirecutter team emphasizes safety and developmental appropriateness — attributes the Nuby shares, with its BPA-free, non-toxic materials and easy-grasp design for 3-month-olds. This makes the Nuby a recommended alternative for parents who don't need the prestige of Sophie.

Frequently Asked Questions
Is the Nuby IcyBite Keys worth $4.28?
Yes, for parents of early teethers. Over 110,000 reviews and a 4.7 rating confirm it’s a reliable, fridge-cooled soother that babies love. It’s one of the best values under $5, though heavy chewers may outgrow it quickly. Many parents report that keeping a spare set in the fridge ensures there's always a cold one ready.
How does the Nuby IcyBite Keys compare to Sophie the Giraffe?
Both offer teething relief, but the Nuby uses gel cooling while Sophie relies on rubber texture. The Nuby costs under $5 versus Sophie’s $25, making it far more budget-friendly. Sophie is a keepsake; the Nuby is a practical starter. If you're looking for a first teether without commitment, the Nuby is the clear winner.
What problems does the Nuby IcyBite Keys have?
The main issue is gel leakage if chewed too hard—if your baby is a strong chewer, the key may puncture. It’s also hand-wash only, not dishwasher safe, and lacks the textured surface older teethers need. Regularly check for bite marks to prevent gel exposure and discard if compromised.
Can I put the Nuby IcyBite Keys in the dishwasher?
No, they are hand wash only. Use mild soap and warm water, and avoid abrasive scrubbers to preserve the plastic’s integrity. For quick sanitizing on the go, you can use steam bags, but avoid boiling.
What age is the Nuby IcyBite Keys suitable for?
It’s designed for babies 3 months and older. The key ring is sized for tiny hands, and the BPA-free silicone is safe once babies start mouthing objects. Some babies start teething as early as 2 months, so you can introduce it under supervision even then.
Is the Nuby IcyBite Keys BPA-free?
Yes, Nuby states the teether is made from safe, non-toxic materials and is BPA-free, meeting government safety regulations. To maintain safety, replace the teether every few months with heavy use.
