Newborn Essentials Checklist: What You Actually Need
If you're expecting a baby and feeling buried under conflicting advice about what to buy, you're not alone. Every newborn essentials checklist you find online seems to include thirty more items than the last, and half of them turn out to be things you never use. The reality is that newborns need far less than the baby industry would have you believe — and getting the basics right matters more than ticking every box on a registry.
This is the checklist we wish someone had given us: what you actually need for the first six weeks, what's nice but not necessary, and what you can confidently skip. No filler, no affiliate links to things you'll regret buying — just honest advice from a brand that makes the one item every newborn genuinely can't do without.
The Clothing Essentials (and How Many)
Newborn clothing lists tend to spiral. Five vests, seven sleepsuits, three cardigans, two hats, four pairs of scratch mitts — before you know it you've spent a small fortune on clothes your baby will wear for six weeks at most. Here's what actually gets used.
Bodysuits are the foundation. They sit flat against the skin, layer under everything else, and handle the relentless cycle of milk, sick, and nappy leaks that defines the first weeks. You need six to eight — enough that you're not doing laundry every single day but not so many that half of them never leave the drawer. Choose long-sleeve for winter babies, short-sleeve for summer, and prioritise organic cotton if your baby will be in them all day (and night). A bodysuit in GOTS-certified organic cotton, like the ones in Sleep No More's range, removes any worry about chemical residues against brand-new skin.
Sleepsuits are next. Four to six will do. Look for ones with built-in scratch mitts or fold-over cuffs — they save you buying separate mitts that fall off within minutes anyway. A couple of cardigans or zip-up layers for cooler days round out the wardrobe. That's it for clothing. Seriously.
Sleep Essentials
Safe sleep advice changes often enough that it's worth checking the latest guidelines from the Lullaby Trust (UK) or the AAP (US), but the essentials themselves are straightforward. You need a firm, flat mattress that fits the cot or Moses basket snugly, with no gaps around the edges. You need fitted sheets — three or four, because night-time leaks are inevitable. And you need a sleeping bag or swaddle appropriate for the room temperature.
A Moses basket or bedside crib is genuinely useful for the first few months. Babies sleep better within arm's reach, and you'll appreciate not having to walk to another room for night feeds. A full-size cot can wait — most babies don't move into one until three to six months, and by then you'll have a better sense of what works for your family.
What you don't need: a top-of-the-range cot mobile, a white-noise machine shaped like an owl, a sleep-tracking sock, or a heated mattress pad. Some of these are lovely; none of them are essential. A consistently dark room and a simple bedtime routine will do more for your baby's sleep than any gadget.
Feeding and Changing Basics
Whether you're breastfeeding, bottle-feeding, or combining both, a few items will be in constant rotation. If breastfeeding, a nursing pillow makes the early days significantly more comfortable — you're feeding eight to twelve times a day. Muslin cloths are non-negotiable: you'll use them to catch posseting, as a light blanket, as a changing-mat cover, and as a makeshift bib. Buy at least ten. They're cheap, they wash easily, and you will always need one more than you think.
For changing, a waterproof mat — even a basic folding one — is all you need. A mat on the floor works perfectly well and has the added benefit of being impossible to fall off. Stock up on nappies in newborn and size one (your baby will move through newborn size faster than you expect), a good barrier cream, and cotton wool or water wipes for the first weeks.
The Nice-to-Haves (Not Essential)
Some items fall into the category of genuinely useful but not strictly essential. A baby carrier or sling lets you hold your baby close while keeping your hands free, and many newborns settle better when worn than when put down — but it's worth trying different styles before committing to an expensive one.
A bouncer chair gives you somewhere safe to put the baby down while you eat or shower. A baby monitor is helpful if the baby sleeps in a different room, but unnecessary if you're using a bedside crib. A pram is obviously important, but you won't use it much in the first fortnight — buying second-hand is sensible for something outgrown fast.
Gift sets that combine a few essentials — bodysuits, a muslin, a keepsake toy — can be a smart way to cover several bases at once. Sleep No More's gift bundles pair organic-cotton bodysuits with personalised extras, giving you a ready-made starter kit.
What You Can Skip or Borrow
This is the section that will save you the most money. Newborn shoes are decorative only — babies don't walk and their feet develop better without them. A nappy bin with special refill cartridges is unnecessary when a regular pedal bin works just as well. A baby bath can be replaced by the sink or the regular bath with a non-slip mat. And wipe warmers are a solution to a problem that doesn't exist.
Scratch mitts fall off constantly, and most sleepsuits with fold-over cuffs make them redundant. Newborn hats are only needed outdoors in cold weather — indoors, a hat can cause overheating, which is a greater risk than a cold head.
The golden rule: if someone you trust offers to lend something, say yes. Moses baskets, baby baths, and bouncer chairs have a short useful life. Borrowing is practical, economical, and better for the planet.
Frequently Asked Questions
How many bodysuits does a newborn need?
Six to eight is the sweet spot. That gives you enough to manage a couple of outfit changes a day without running the washing machine every evening. Prioritise quality over quantity — a well-made organic-cotton bodysuit will outlast three supermarket ones and feel far better against newborn skin. If you're buying ahead, choose a mix of newborn and 0–3 month sizes, since some babies skip the smallest size entirely.
What size should I buy for a newborn?
Most full-term babies fit "newborn" or "up to one month" for the first few weeks, then move into 0–3 months. If your baby is predicted to be on the larger side, it's worth having a few 0–3 month pieces ready from the start. When in doubt, size up — a slightly roomy bodysuit still works, but one that's too small is uncomfortable and unwearable. Check each brand's size guide, as sizing varies significantly between manufacturers.
What's overrated on most newborn lists?
Dedicated changing tables, nappy disposal systems with proprietary refills, newborn shoes, wipe warmers, and elaborate cot mobiles top the list. They're marketed as essentials but used briefly — or not at all. A changing mat on a flat surface, a regular bin, and bare feet will serve you just as well. Spend the savings on things that genuinely get used every day, like high-quality bodysuits and muslins.
When should I buy newborn clothes — before or after birth?
Buy the basics before — six to eight bodysuits, four to six sleepsuits, and a couple of layers. You'll want these ready when you come home from hospital. But hold off on buying too much in the smallest size, because you won't know your baby's actual size until they arrive. Many parents find that a few well-chosen pieces in newborn and 0–3 months, supplemented by gifts from friends and family, cover the first weeks comfortably. If you'd like a curated starting point, a gift bundle takes the guesswork out of building that first set.
The best newborn essentials checklist is a short one. Focus on what your baby will wear, where they'll sleep, and how you'll feed and change them — everything else can wait until you know what your particular baby actually needs. Start with the foundation: a handful of soft, well-made bodysuits in organic cotton, a safe sleep setup, and the confidence to ignore the rest.
