Australian Nursery Essentials: 20 mm Mattress Rule and Curated Bundles

Cot mattress thickness check in nursery
Table of Contents

    Before baby arrives, you need four things sorted: a safe sleep surface with a firm, well-fitted mattress and fitted sheet, a change area stocked with nappies, a feeding spot that’s comfortable at 3am, and a small stack of clothes and swaddles. Keep the cot clear and room-share for the first 6 to 12 months, as Red Nose recommends. The full checklist below breaks every item down so you can shop with confidence.

    Sleep essentials for the nursery

    Sleep is where most nursery budgets and most nursery worries go, and for good reason. The surface baby sleeps on matters more than almost anything else in the room.

    Stick to a household cot, a portacot, or a bassinet. Loungers, rockers and inclined sleepers are not designed for overnight or unsupervised sleep. If baby dozes off in one during the day, move them to their flat, firm sleep surface as soon as you can, according to Product Safety Australia’s guidance.

    New sleep products sold from 2026 must meet the Australian Consumer Goods (Infant Sleep Products) Safety Standard 2024. This covers cots, bassinets and labelling for products that aren’t meant for sleep, so check for compliance markings before you buy.

    The mattress needs to be firm and fit snugly, with no more than a 20 mm gap between the mattress edge and the cot sides, a detail confirmed in the ACCC’s household cots guide. Pair it with a waterproof protector and a fitted cot sheet that won’t bunch or come loose overnight.

    Keep the cot itself simple:

    • A firm mattress with a snug fit and no gaps wider than 20 mm.
    • One fitted sheet, nothing loose or draped.
    • No pillows, bumpers, cot toys or hanging mobiles within reach.
    • A sleep bag with the right TOG rating instead of loose blankets.
    • A clear zone around the cot, away from blind cords, heaters and furniture that could tip.

    Red Nose recommends room-sharing, baby on their own safe surface in the same room as a parent, for the first 6 to 12 months, because it’s linked to a lower risk of sudden unexpected death in infancy. It also makes night feeds and quick checks far easier, so factor it into where the cot actually goes.

    Pro Tip: Position the cot against an internal wall, away from windows, blind cords and heaters, so you never need to think twice about what’s near baby while they sleep.

    If you’re after more detail on setting the room up calmly from day one, our nursery sleep advice covers the basics in plain language.

    Feeding essentials for the nursery

    Feeding happens in the nursery as often as sleep does, especially overnight, so the setup needs to work half-asleep and in the dark.

    A comfortable chair or glider is worth the floor space. Put a side table or caddy next to it so burp cloths, water and whatever else you need are within reach, not three rooms away. A warm, dimmable light matters more than people expect: bright overhead lighting at 2am makes it harder for everyone to get back to sleep.

    For bottle feeding, you’ll want:

    • Bottles in a couple of sizes, plus a steriliser or a reliable hot-water-and-brush routine.
    • A dedicated bottle brush, kept separate from other kitchen tools.
    • A simple system for storing made-up formula safely and warming it without overheating.

    For breastfeeding, the shortlist looks different:

    • A nursing pillow to support positioning and reduce arm strain.
    • Breast pads and a stash of burp cloths for the inevitable spills.
    • Water within reach, because feeds are thirsty work.

    Whichever path you’re on, washable covers and a basket to separate clean items from used ones save a surprising amount of friction. A parenting app like Naluna can help you track feeds and sleep patterns in the early weeks, which takes some of the guesswork out of whether baby’s routine is settling.

    Nappy and changing area essentials

    A functional change area is less about gear and more about having the right things close enough that you’re not improvising mid-change.

    1. Choose your surface: a fixed change table keeps things consistent, while a portable change mat on the floor or a low bed removes any risk of a fall from height. If you do use a raised surface, never step away, even for a second.
    2. Stock nappies in bulk from the start. Newborns can go through a lot in the first weeks, so buying ahead saves a late-night supermarket run.
    3. Keep wipes, nappy balm and a change of clothes in the same spot as the nappies, not scattered across the house.
    4. Sort your nappy disposal: a sealed nappy bin reduces odour and keeps the room pleasant between bin days.
    5. Set up a laundry plan for cloth nappies or soiled clothes before you need it, not after.

    Keep a nappy caddy within arm’s reach of the change surface, and use open shelving for the things you reach for daily. A small go-bag, pre-packed with nappies, wipes and a spare outfit, means you’re never scrambling before you leave the house.

    Pro Tip: Pack the go-bag the same night you set up the nursery, and restock it the moment you get home from an outing, not the next time you need it.

    Clothing, swaddles and small bedding essentials

    Newborn clothing doesn’t need to be extensive, but it does need to be practical and easy to wash on repeat.

    A sensible starter stack covers:

    • Five to seven bodysuits or onesies, since blowouts happen.
    • A handful of singlets for layering under sleep suits.
    • Three or four zip-up sleep suits for easy night changes.
    • Socks and a couple of light, breathable hats for cooler days.

    Swaddling can help settle a newborn, but it comes with rules. Use lightweight, breathable fabric, swaddle firmly around the body but leave room at the hips, and stop swaddling once baby shows signs of rolling, usually somewhere in the first few months. From there, a sleep bag is the safer option.

    Keep a couple of spare fitted sheets and waterproof protectors on hand for the inevitable overnight leaks. Loose blankets and pillows stay out of the cot altogether, no matter how soft or decorative they look.

    Travel and larger equipment

    The big-ticket items get the most attention in a baby registry, and they’re worth getting right the first time.

    A newborn-compatible car seat is non-negotiable before you leave the hospital or birth centre. Check it meets current safety requirements and, if you’re not confident fitting it yourself, get it checked by a professional installer.

    For the pram, prioritise a few practical features over anything else:

    • A newborn recline position, since young babies can’t sit upright.
    • Brakes that are easy to engage one-handed while holding baby.
    • A fold that’s manageable solo, especially if you’re getting in and out of a car often.

    Ergonomic baby carriers give you hands-free options for settling baby or getting around the house. Whichever carrier you choose, make sure baby is positioned upright, close enough to kiss, with their airway clear.

    A portacot earns its place if you travel, visit family, or need a second sleep space downstairs. Check the locking mechanism every time you set it up, and only use a mattress made for that exact model, since even a small gap can create a hazard, as the portable folding cots guide notes.

    Portacot mattress fitted inside its base

    Pro Tip: Fit the car seat and test the pram fold before baby arrives, not in the hospital car park with a newborn in your arms.

    Storage, organisation and night-time setup

    A nursery that works at 2am is one where nothing requires thought.

    1. Place the feeding chair close to the cot so night feeds don’t involve carrying a half-asleep baby across the room.
    2. Keep nappies, wipes and spare clothes within arm’s reach of the change area, every single time.
    3. Leave a clear, obstacle-free path from the door to the cot for groggy middle-of-the-night checks.
    4. Use baskets for bulky, infrequent items and labelled drawers for daily essentials, so you’re not hunting in the dark.
    5. Set up blackout curtains for day naps and keep any lamp out of baby’s reach but close enough for you to use one-handed.

    A spare fitted sheet folded and ready, plus a waterproof mat under the change area, means a middle-of-the-night blowout doesn’t turn into a full reset. Our calm nursery checklist walks through more of these small setup decisions.

    Safety and compliance every parent should check

    A handful of checks make the difference between a nursery that looks right and one that actually is.

    Every new sleep product bought from 2026 onward must meet the Australian Consumer Goods (Infant Sleep Products) Safety Standard 2024. Cot bar spacing should sit between 50 mm and 95 mm, with the mattress fitting to within a 20 mm gap, according to a Product Safety Australia cot safety alert. Gaps outside that range can trap limbs or snag clothing.

    Red Nose’s core safe sleep advice is worth pinning somewhere visible:

    • Always place baby on their back to sleep.
    • Room-share for the first 6 to 12 months.
    • Keep the cot clear of pillows, bumpers, toys and loose bedding.
    • Secure blind cords well above reach, at least 1.6 metres off the floor.

    Buying second-hand is common and perfectly fine, as long as you check it properly. Bring a tape measure, confirm bar spacing and mattress fit tolerances, and ask for proof the item complies with current standards before you hand over any money.

    A few other hazards are easy to miss once the nursery is decorated and feels finished:

    • Blind and curtain cords anywhere near the cot.
    • Loose bedding, soft toys or cushions left inside the cot.
    • Electric heaters or heated items placed close to the sleep surface.
    • Unanchored furniture that baby could pull over once they’re standing.

    Anchoring furniture is one of those steps that’s easy to skip because baby isn’t mobile yet, but it matters later, and it costs almost nothing to do now.

    Consolidated nursery essentials checklist

    Here’s everything from above, grouped so you can shop in order of priority.

    Must-have, before baby comes home:

    1. Cot or bassinate with a firm, properly fitted mattress and fitted sheet.
    2. Nappies (start with a bulk pack), wipes and a change mat.
    3. A feeding chair, bottles or breastfeeding supports, and burp cloths.
    4. Five to seven bodysuits, a few sleep suits, socks and hats.
    5. A newborn-compatible, correctly fitted car seat.

    Useful in the first few months:

    • A sleep bag in the right TOG for the season.
    • A nursing pillow or glider for feeding comfort.
    • A nappy caddy and a labelled storage system.
    • Blackout curtains and a dimmable night light.

    Optional or for later:

    • A baby carrier for hands-free settling.
    • A portacot for travel or a second sleep space.
    • Mobiles and soothing toys, kept well out of the cot.

    Quick-trip bag, packed and ready:

    • Nappies, wipes and a spare outfit.
    • A muslin cloth or burp cloth.
    • A small blanket for the pram, never for the cot.

    Honey & Sage curated picks: how curated bundles reduce decision fatigue

    Baby registries can balloon into hundreds of line items fast, which is exactly the problem Honey & Sage was built to solve. Instead of an endless catalogue, products are curated by mothers around what actually gets used in the early days.

    A few examples that map straight onto the checklist above:

    • The Cosy Baby Boy Gift Bundle covers newborn clothing basics in one go, useful for the “must-have” clothing stack without piecing it together item by item.
    • Little Comforts for Mum looks after the parent during feeding and recovery, which is easy to overlook when every other list is about the baby.
    • The Safe Sleep range supports the sleep setup covered earlier, fitted sheets and bedding chosen with the safety rules above in mind.

    Curated bundles won’t replace checking compliance labels yourself, but they take a decent chunk of the decision-making off your plate.

    What to buy first if you’re short on time or money

    If you can only sort a few things before baby arrives, sort safety first: the sleep surface, the mattress fit, and the car seat. Everything else can be bought in the first fortnight.

    If money’s tight, spend on the mattress and car seat, and borrow or buy second-hand for clothes and the pram, checking compliance on anything pre-loved. If time’s tight, skip the browsing and buy a pre-assembled bundle for clothing and bedding, then spend your saved hours on the nappy station and car seat fitting instead. Either way, the printable checklist above and a curated starter bundle will get you further, faster, than another hour of scrolling.
