Naps on the move: meet the Zello Portable Pro Max

A small, rechargeable sound machine and night light designed to bring a bit of bedtime calm to pram naps, car journeys and nights away. Here's what it does, and how to use one sensibly.

Every parent knows the nap that goes beautifully at home and falls apart the moment you leave the house. Different room, different noises, a dog barking three gardens away. Consistency is a big part of a calm bedtime routine, and it's usually the first thing to go when you're out and about.

That's the gap the Zello Portable Pro Max is designed to fill: a compact, rechargeable sound machine and night light that travels with you, so the familiar sounds of your baby's wind-down routine can come too.

What it does

It packs a lot into a small, lightweight gadget. There are 30 soothing sounds to choose from, including white noise, fan, nature sounds and lullabies, plus a warm night light with seven colour options and adjustable brightness. The volume is adjustable, and a timer can be set for 30, 60 or 90 minutes, or left running continuously.

The buttons light up, which sounds minor until you're fumbling for them at 2am without wanting to switch the big light on.

Built for home and away

The headline feature is the battery. Zello says it lasts up to 50 hours on a single charge, so it can cover a run of naps, days out and nights away without hunting for a plug. It's rechargeable, light enough to live in the changing bag, and designed to clip on to a pram or car seat.

Holidays, grandparents' houses, the travel cot squeezed into the corner of a hotel room: this is where a familiar sound can help things feel the same, even when everything else isn't.

A familiar sound won't fix everything. But on a noisy day out, it's one less thing that's different.

How to use it sensibly

A sound machine is part of the room, not part of the bed. Zello's own guidance is to keep the device out of the cot and away from your baby's head, and to keep the volume moderate: they suggest around 65dB with the machine positioned roughly 50cm away. On the pram or car seat, place it so it isn't right beside your baby's head.

The basics of safer sleep apply wherever you are. The Lullaby Trust advises placing your baby on their back on a firm, flat mattress with the space kept clear, and moving them to a firm, flat surface if they fall asleep in something inclined.

Who it's for

Parents who are out and about a lot, travel often, or have a baby who likes things just so. It's also a neat option for families who already use a sound as part of bedtime at home and want the same cue on the go. At £28.99, it sits at the friendly end of the baby gadget spectrum.

What it isn't is a magic sleep button. No gadget can promise a baby will sleep, and anyone who says otherwise has probably never met a baby. Think of it as one small, useful piece of a calm, consistent routine.

If you’re trying to conceive (TTC), you probably know that there are certain foods and nutrients that become especially important once you’re pregnant. But nutrition plays a vital role even when trying to conceive, much like laying a strong foundation before constructing a house.

Certain nutrients create that foundation by supporting egg and sperm health (yes, nutrition matters for both partners), hormone balance and creating a hospitable environment for a fertilized egg to implant. In fact, studies show that certain nutrients can help increase fertility and improve success rates for both natural conception and fertility treatments.

‍

In other words, nutrition is a key player in the TTC journey, but getting the right nutrients in the right quantities can be tricky. That’s where supplements come in. Just as you’d take a multivitamin to fill in nutritional gaps for optimal health, fertility supplements can give you that extra nutrient boost.
