Baby's first toothbrush that halves brushing time: Radius Pure Baby
In short
Radius Pure Baby is a soft first toothbrush for babies around their first birthday whose teeth have not all come in yet. A mom with a baby about to turn one used Radius Pure Baby along with the Radius Tots and Tots Plus brushes and found the bristles soft, the handle easy to grip, and brushing time cut in half thanks to a head about twice the size of a regular toothbrush. Radius Pure Baby is a little pricey, but she confidently recommends it as a baby's first toothbrush.

Why I chose Radius as my one-year-old's first toothbrush
The Radius baby toothbrush is the one I picked when we started brushing properly around the first birthday. I'm a mom of a nearly-one-year-old now... hehe... My baby has already lived almost a whole year! So proud, so touched. It was finally time to start the brushing I'd put off and put off, so I bought the Radius baby toothbrush that's famous among moms.

Honestly, Radius is a bit pricey, so I hesitated a little when buying. But my baby's teeth haven't all come in yet and the gums are so fresh and tender that I worried about hurting them, so I went with Radius, which is said to be incredibly soft!


Where to buy the Radius toothbrush, plus delivery and packaging
I bought the Radius toothbrush at Onnuri Store! They sell all sorts of products, so window-shopping was fun too, and both the product and the delivery were quick!!

The parcel arrived in perfect shape, no damage at all :)

The brush was carefully packed, rolled up in bubble wrap~

Pure Baby, Tots and Tots Plus: what's different at each stage?
Radius toothbrushes come in stages by age. I was going to buy only Pure Baby, the stage my baby can use now, but I also got Tots, which is for 18 months and up! And while I was at it, I got Tots Plus too, for ages 3 to 8, to give to a friend's baby!!

Radius is a brand any mom has probably heard of at least once. It's been steadily popular among moms :) I hear the Radius brand has been around for 40 years already. Brands that last that long clearly have their reasons~ haha

What makes a good toothbrush for a baby?
A baby toothbrush should remove plaque effectively without damaging the tissues in the mouth. It also has to be easy for kids who are still clumsy at brushing. The Radius baby toothbrush ticks all of those boxes!

Radius toothbrush design
First off, the Radius design totally wins moms over... They really know how to use color. They're primary colors but not tacky at all, nicely balanced, the kind of brush you want to keep as a keepsake. Even just casually left in the bathroom it has real presence, and when the baby holds it and brushes, it's sooo adorable ^_^

Is Radius Pure Baby easy for little hands to hold?
I thought Radius Pure Baby was perfect as the first toothbrush for babies under one! The first reason is how well it fits in a baby's hand. The grip is stable, so it looked comfortable even for kids brushing for the first time.

The handle is easy to hold, so when the baby tries to grab it on their own, it sits securely in the hand. That was the best part, I think!

Does a bigger head shorten brushing time?
The head of the Radius baby toothbrush is about twice the size of a regular toothbrush, and brushing time really was cut in half. Oh! And there's one more plus: the big head!!! It cleans a larger area in one pass, so brushing goes faster!
I used a small toothbrush before, and my baby would scream and cry during brushing... T_T I wished I could shorten the time, and after switching to Radius it dropped by half! Hehe...

The toothbrush the baby picked
Maybe a sense of self is starting to develop... baby only feels satisfied choosing their own things... haha. Okay, which one do you want? You pick!

Look at that very careful choosing... so cute!

Is the Radius baby toothbrush material safe?
The Radius baby toothbrush is BPA-free, so no worries about endocrine disruptors!!! It also uses plant-based nylon, so I'd really recommend it as a baby's first toothbrush :)

Mommy. I picked this one. From today I'll brush really hard with it.

Soft bristles
When I opened the Radius toothbrush and touched it, the bristles were so soft. Everything about babies is delicate, right? Gums too... T_T It gently protects my baby's silken-tofu gums!

A toothbrush goes straight into the mouth, and kids suck, chew and bite on it, so I was extra worried, but with Radius I can hand it over without worry, which is a relief haha

Verdict: recommended for babies brushing for the first time
If your baby is brushing for the first time, it'll feel awkward and unfamiliar, but I can confidently recommend the Radius baby toothbrush~!
