The list below is deliberately short — it covers only the handful of items where getting the specific choice wrong causes a real problem in the first weeks, not a copy of a department store's full baby aisle. Everything else can wait, or be bought secondhand.
By UK law, a newborn must travel in an appropriate car seat from their very first car journey — there's no grace period for "just this once." Many maternity units also expect to see one fitted correctly before discharge, so this needs sorting before the due date, not after. An infant car seat like the Cybex Cloud T or Cloud G, rated from birth to around 76cm, is the version to buy first — you'll move up to a bigger seat later, so there's no benefit to buying anything that claims to "grow with" a newborn at this stage.
Fit the car seat in your actual car and test it before the due date — a seat that doesn't click cleanly into your specific car's ISOFIX base is a problem worth finding weeks early, not in a hospital car park.
NHS guidance recommends a baby sleeps in the same room as you, on a firm flat surface, for at least the first six months. A Moses basket, a bedside crib like the Chicco Next2Me, or a full-size cot all satisfy this — which one to buy mostly comes down to how long you want it to last. A bedside crib that attaches to your bed makes night feeds easier without you leaving the bed; a Moses basket is more portable around the house but gets outgrown faster.
A crib you'll use for six months often costs about the same as a Moses basket you'll use for three — factor in how long each option actually lasts, not just the price tag.
A newborn needs to lie completely flat, so a pushchair only works from day one if it takes a carrycot, has a genuine lie-flat seat, or comes as part of a travel system with a compatible infant car seat — a seat that only reclines partway isn't suitable yet. Something like the Joie Litetrax Pro or Silver Cross Pop 2 covers the essentials without paying for features a newborn won't use for months.
Check the specific model's lie-flat or newborn rating before buying, not just the brand's general reputation — some pushchairs in the same range aren't newborn-ready even when a very similar model is.
Nothing exotic here — a change mat like Avery Row's, a stack of newborn-size nappies, and a nappy bin such as Tommee Tippee's Twist & Click cover the basics. Newborn-size nappies run small and get outgrown within weeks, so a giant box bought before the birth is a common overbuy.
Buy the smallest pack of newborn-size nappies you can find rather than bulk-buying — most babies move up a size within 2-4 weeks, and unopened bulk packs in the wrong size are hard to use up.
Vests, sleepsuits and a couple of cardigans in newborn and 0-3 month sizes cover the first weeks. Buying heavily into "newborn" size specifically is often wasted money, since many babies move into 0-3 months within the first fortnight.
Buy fewer newborn-size items and more in 0-3 months — you'll get more actual wear out of the bigger size.
Even an exclusively breastfeeding household benefits from a couple of bottles and a way to sterilise them — for expressed milk, formula top-ups, or a night feed someone else covers. A starter set like Tommee Tippee's Advanced Anti-Colic range, plus a steriliser (microwave versions like Tommee Tippee's are the cheapest option, electric ones need no microwave but cost more), covers this without needing every bottle-related product on the market.
One steriliser and 4-6 bottles is enough to start — buy more only once you know which bottle shape your baby actually takes to.
Not a legal requirement, but genuinely useful once the crib moves to its own space — an audio-only monitor is enough in a flat or small house, while a video monitor like VTech's or Owlet's earns its higher price when the nursery is on a different floor from where you'll be.
Match the monitor to your actual layout, not the most-reviewed model — an audio monitor in a one-bedroom flat does the same job as a £150 video system.
A baby bouncer, a full toy set and shoes are all things that can wait — a newborn can't sit up, doesn't play with toys in any meaningful way for months, and won't need shoes until walking starts.
Hold off on anything a newborn can't physically use yet — it's easier to buy once a real need shows up than to store gear that sits unused for months.
FAQ
Do I need a car seat before the birth, or can I buy one after?
Before — UK law requires an appropriate car seat from a baby's first car journey, and many hospitals expect to see one fitted correctly before discharge. Buy and fit it before the due date, not after.
Is a Moses basket or a full crib the better first purchase?
It depends how long you want it to last — a Moses basket is portable but usually outgrown by 3-4 months, while a bedside crib or cot lasts closer to six months or longer. See "Somewhere Safe for Baby to Sleep."
Can any pushchair be used from birth?
No — a newborn needs to lie flat, so only pushchairs with a carrycot, a genuine lie-flat seat, or a compatible infant car seat attachment work from day one. Check this against the specific model, not just the brand.
How many newborn-size clothes do I actually need?
Fewer than most checklists suggest — many babies outgrow newborn size within two weeks, so it's worth buying more in 0-3 months and less in newborn size specifically.
