As a mum to a baby and toddler, and a pharmacist, I’m fairly hard to impress when it comes to feeding gear and teething products. Most of it promises to change your life and ends up on the “things-that-sounded-better-than-they-are” pile of things you wish you hadn’t bought. Boobcube is one of the rare exceptions that’s earned a permanent spot in our freezer.

We tested the Ultimate Boobcube Bundle ($74.95), which includes the Boobcube Tray, the Pop Feeder (with three interchangeable nipple sizes), a Safety Strap, and a Storage Container. On paper it’s a simple concept: freeze breastmilk, formula, fruit yoghurt or puree into cubes, then pop them into the silicone feeder for teething relief or mess-free snack. In practice, the details are what set it apart.

Why It Works from Birth

Boobcube is designed for use from  birth, as part of a 4-in-1 teething and development system. From day one, the handle doubles as a sensory grab ring, supporting  dexterity and fine motor skill development alongside a teething ring for sore gums. From three months, you can introduce the smallest nipple size, which makes it a safe first step towards solids down the track, and every component is tested to Australian and New Zealand standards.

The Tray: Bigger Capacity, Less Refilling

The tray has 10 cavities, compared to the 4 I’ve seen in other brands. That might sound like a small thing, but if you’ve ever been stuck refilling and refreezing a tiny tray every other day, you’ll know it’s not. Ten cubes at a time means I can batch-freeze breastmilk or puree and not think about it again for days. The cubes are also designed to fit perfectly into the Pop nipples.

The dedicated storage container is another detail that I really appreciate about this product. Having a proper container to keep the frozen cubes organised in the freezer makes it feel tidier and more hygienic than cubes in a zip-lock bag.

Safety-First Feeder Design

The frozen cubes sit inside the silicone Pop Feeder rather than going straight onto bub’s gums. That matters, because a hard block of ice straight onto developing gums can do more harm than good. The silicone nipple’s flexible slits keep the food contained and gives baby something safe to gnaw on, without the ice-on-gum contact.

It also means you can safely offer foods that would otherwise be a choking risk — blueberries being a popular choice with our toddler.

The Strap: Longer, and Not Just for the Pram

The safety strap is longer and more fully adjustable than others I have used, and loops onto the pram, the carrier, or high chair — not just the pram straps like some competitor versions. It works for the dummy, the Boobcube pop, toys and cups, which means less bending down to rescue a dropped teether every five minutes.

It’s Not Just a Baby Product

My 2.5-year-old has been loving the feeder too, with frozen blueberries being the current favourite. She’s even happy to chew on it without anything loaded inside, using it as a gum massage tool. The ring on the feeder is ridged for exactly this, and it’s an easy shape for little hands to grip.

That’s really the point of difference with Boobcube: most brands offer one nipple size, and your baby outgrows the product within months. Boobcube comes with small, medium and large sizes, so it actually grows with your child instead of becoming freezer clutter by six months.

Durability

After regular use from a teething baby and a toddler who likes to yank the feeder in and out of her mouth, there are no marks, tears, or missing pieces. Compared to other feeders we’ve been through, this one just feels more considered — it effectively replaces four separate products, (a teething ring, a grab ring, a teething soother, and an introduction to solids) with a bigger tray, a sturdier handle, a longer strap and multiple nipple sizes, where most competitors give you one of those features at most.

A Pharmacist’s Note on Safety

A few things worth knowing if you’re using a tray-and-feeder system like this:

Freezing and Storing Breastmilk

The Australian Breastfeeding Association’s guidelines are that freshly expressed milk is fine at room temperature (26°C or below) for 6-8 hours, and in a deep freezer (-20°C) for 6-12 months. Milk that’s been frozen and thawed should be used within 24 hours in the fridge or 4 hours at room temperature and shouldn’t be refrozen once fully thawed — though milk that’s only partially thawed, with ice crystals still present, can be safely refrozen. The ABA also recommends filling containers no more than three-quarters full to allow for expansion and freezing in small portions to avoid waste — both of which line up well with how a multi-cavity tray like this is designed to be used.

Choking Risk

The feeder is designed so nothing can come apart, which removes the choking risk you’d otherwise worry about with loose ice or whole pieces of fruit like blueberries.

Cleaning and Sterilising

Sterilise before first use, then wash after every use in warm soapy water or in the dishwasher’s top rack, with a re-sterilising after any illness. Silicone handles boiling, steam sterilising, and UV sterilisers well — because it’s heat-stable and non-porous, which also makes it less likely to harbour bacteria than a scratched plastic alternative.

What I Don’t Reach For

As a pharmacist, there are a few teething “remedies” I steer clear of — teething gels (especially anything with an anaesthetic in them), a dummy dipped in honey or jam, amber beads, or aspirin, ever. When the pain is bad enough that gum massages and cold therapy aren’t cutting it, paracetamol dosed exactly to what is on the pack for age and weight is the option I reach for instead.

The Verdict

Boobcube isn’t reinventing the wheel — frozen fruit and food feeders aren’t a new idea. What sets them apart is how much thought has gone into the details that matter day to day: capacity, strap  length, and sizing that grows with the child. It was put to the test properly in our house recently when my baby and toddler decided to teethe at the same time — two kids, two Boobcubes, and both settled. Anyone with a little person in the house with sore gums will know that’s not a small win. It’s the difference between getting some sleep and getting next to none!

Would I recommend it? Honestly, yes! It’s the only piece of teething gear that has kept up with both of my kids at completely different stages and is still on daily rotation in our freezer.
