Newborn Essentials: What You Actually Need
The baby product market is enormous, ingenious, and very good at making you feel that the right purchase will solve a problem you do not yet have. Here is a grounded, honest guide to what actually matters.

The most useful reframe before you buy anything: newborns need warmth, milk, sleep, and you. Almost everything else is about making life more convenient for the adults — and convenience is a legitimate reason to buy something, but it means you can be much more selective than the baby product industry would have you believe.
A second useful principle: buy the essentials before birth, and buy everything else once the baby has arrived and you know what your specific baby needs. Every baby is different. Some will love a swing; many will be indifferent to it. Some will sleep beautifully in a moses basket; others will refuse it from day one. The advice of other parents is useful but not transferable — what transformed someone else's experience may sit unused in your loft.
We bought the fancy baby bath, the wipe warmer, the nappy bin with special bags, the breathing sensor monitor, and the expensive swing. Used: the swing once. Skip the catalogue and buy a very good changing mat, a lot of muslins, and wait to see what your actual baby needs.
The Genuine Essentials
These are the things you genuinely need before the baby comes home. Everything else can wait.
Sleep
- A safe sleep space — a cot, crib, moses basket, or bedside sleeper with a firm, flat mattress. The mattress should be new even if the cot is second-hand, as used mattresses have been associated with a slightly elevated SIDS risk. The sleep space should meet current BS EN 716 safety standards.
- Fitted sheets — at least two or three. Fitted only; no loose bedding.
- Sleeping bags — two in the appropriate tog (1.0 for rooms 20–24°C; 2.5 for rooms 16–20°C). Far safer than blankets, and they cannot be kicked off in the night.
Feeding
- If breastfeeding: a good feeding pillow (not optional — it will save your back and arms through hundreds of night feeds), at least two nursing bras fitted in the third trimester, breast pads, and lanolin nipple cream for the early weeks.
- If formula feeding: at least four bottles (with slow-flow teats for newborns), a bottle brush, a steam steriliser, and a ready supply of first infant formula. Pre-made liquid formula is more expensive but genuinely convenient for the first days home from hospital.
- If undecided: buy the breastfeeding basics and hold off on bottles until you need them. You can usually get bottles within 24 hours if required.
Nappies and changing
- A changing mat — waterproof, with raised edges. This is used many times daily; a good one is worth the investment.
- Nappies — start with a small supply of newborn size (not a bulk buy — many babies move out of newborn very quickly, and some are born into size 1). Stock up on size 1 before the birth.
- Cotton wool or water wipes, nappy cream, and nappy bags
Clothing
Newborns need very little clothing. The hospital bag needs: 3 vests, 3 sleepsuits, a hat, and scratch mitts. At home, add a few more of the same. Long sleeves are not essential — babies do not need to be over-wrapped in a warm house. Avoid anything with ribbons, strings, or elaborate fastenings you will be attempting at 3am.
Travel
- A car seat — non-negotiable if you own or regularly travel by car. Must be rear-facing, Group 0 or 0+ (up to 13kg). Should be new, or second-hand only if you know its full history. Have it fitted and checked by a trained seat fitter before the birth.
- A pram or carrier — one or the other, or both. A carrier (sling) is particularly useful in the fourth trimester for a baby who wants to be held constantly.
The thing I was most glad I bought before birth: a feeding pillow. The thing I most regret not buying: a second feeding pillow for upstairs. The thing I least needed: any toy for under 3 months. They are interested in your face. That's it.
The Useful Extras
These things are not essential but are genuinely useful for many families. Consider them after the birth, once you know whether you need them.
- A bouncy chair — a safe place to put a baby when you need both hands. Do not use it as a sleep surface.
- A play gym or activity mat — useful from around 6 weeks for tummy time and stimulation. Not needed before then.
- A sling or wrap carrier — enormously useful for a contact-needing baby. Try before you buy if possible, or hire one initially, as different styles suit different bodies and babies.
- A breast pump — if breastfeeding, useful once feeding is established (not in the first 2–3 weeks). Your NHS trust may provide double electric pumps for medical need; otherwise, hiring a hospital-grade pump is an option before committing to a purchase.
- A baby monitor — useful from when your baby first sleeps in a different room from you (the NHS recommends room-sharing for 6 months). A basic audio monitor is sufficient for most families.
- A white noise machine — the app version is free and works just as well; a dedicated machine is convenient for travel.
What You Can Buy Second-Hand (and What You Cannot)
Buying second-hand for babies is a sensible, sustainable choice for most things — and there are a small number of items where it genuinely is not.
Always buy new
- Car seat — unless you know the full history of the seat and can confirm it has never been in an accident. Structural damage to car seats is not always visible.
- Cot or crib mattress — a used mattress that has been slept on by another baby may harbour bacteria and has been associated with a slightly elevated SIDS risk in some research.
- Breast pump (personal use items) — open-system pumps are designed for single users. Hire of a hospital-grade closed-system pump is fine.
Perfectly safe second-hand
Cots and cribs (with a new mattress), clothing, prams and pushchairs, bouncers, play gyms, slings (if no structural damage), sterilisers, and the vast majority of toys and equipment. Facebook Marketplace, NCT Nearly New Sales, and Vinted are all good sources. Check for any product recalls before buying.
Things Most Parents Wish They'd Skipped
With the benefit of hindsight — and a great deal of input from the communities that have gone before you — here are the things that consistently fail to justify their cost or the space they take up.
- Nappy bin with branded bags — a lidded bin lined with normal bin bags works just as well.
- Wipe warmer — babies adapt quickly to room-temperature wipes, and warm wipes can encourage nappy-off time by making it feel pleasant.
- Expensive changing table — a good changing mat on any flat surface (floor, dresser, bed) is equally functional and safer in some respects.
- Shoes for pre-walkers — babies do not need shoes until they are walking outdoors. Bare feet support natural foot and gait development. Soft socks are all they need indoors.
- Gadgets that "guarantee" sleep — no product can guarantee that a baby will sleep. Products that suggest otherwise are marketing, not medicine.
- Novelty items and single-use gadgets — bath thermometers (your elbow works fine), formula dispensers with overcomplicated mechanisms, and equipment that serves only one developmental stage for a matter of weeks.
Many people wait until after the 20-week scan to begin buying significant items. There is no clinical reason not to start earlier, and waiting until after 20 weeks is partly emotional — the scan provides meaningful reassurance. If you have a specific reason to wait longer (such as a history of loss or ongoing pregnancy concerns), that is entirely understandable. The essentials can be bought relatively quickly, and online delivery means there is no logistical need to buy everything months in advance.
For bottle-feeding equipment and dummies, yes — sterilising is important until your baby is 12 months old, as their immune system is still developing. Breast pump parts that come into contact with milk also need sterilising. General baby equipment, toys, and clothing do not need sterilising — a normal wash is sufficient. Sterilising can be done by steam (electric steriliser or microwave steriliser), cold water chemical sterilisation, or boiling for 10 minutes.
This is genuinely unpredictable, as it depends on your baby's size. Newborn clothing fits babies up to approximately 7.5–8.5lbs (3.4–3.9kg). If there is any indication your baby may be larger than average, buy directly in size 0–3 months. Many babies, particularly those born close to or after their due date, skip newborn size entirely. It is worth buying only a small quantity of newborn clothing before the birth.
For many families, yes — particularly if you are breastfeeding or if your baby is one who wakes frequently in the night. A bedside crib (such as a SnüzPod or Chicco Next2Me) sits flush with the adult bed and allows you to reach your baby, feed, and resettle without fully getting up. They support room-sharing while keeping the baby on a separate sleep surface. They are expensive new, but hold their value well second-hand (with a new mattress).
