As a parent who's tried countless teething toys, this Montessori sensory teether stands out in both design and functionality. The moment I unboxed it, I was impressed by the vibrant colors and varied textures - no wonder my 7-month-old instantly grabbed it!

The soft silicone balls are perfect for gnawing, and I've noticed my baby alternates between different textures depending on gum sensitivity. What surprised me most was how the clicking sound when twisting the halves became an instant hit - it's now our go-to distraction during diaper changes.

While the product claims to be bath-safe, I agree with other reviewers about water getting trapped inside. After one bath trial (with lots of shaking to empty it), we've kept it as a dry-play only toy. The size is ideal for tiny hands - my baby can grip it easily even when fussy.

Cleaning requires some effort (we use a bottle brush for the crevices), but seeing how much relief it provides makes the extra care worthwhile. Pro tip: Boil sterilization works great, just don't exceed the recommended time.

The built-in rattle adds bonus play value beyond teething relief. We've nicknamed ours 'the happy virus' because of how quickly it turns tears into giggles! For parents seeking an effective, multi-sensory teether that grows with baby through different chewing stages, this is absolutely worth trying.
