Walk into any baby store and you would think a newborn needs a small warehouse of equipment.
They don’t. In the first six months, babies need surprisingly few things – but the things they do need, they need to be safe, and a few of them are worth getting right the first time.
This checklist covers what you genuinely need, roughly how many of each, what can safely wait, and – just as importantly – what you can skip entirely.
It reflects current safe sleep and car seat guidance, so you are not buying anything you will later be told to throw away.
Diapering and Bath Time
This is the category you will use most, from day one, many times a day.
- Newborns go through 8-12 diapers a day, so stock up – but don’t over-buy newborn size. Many babies outgrow it within 2-4 weeks. One box of newborn size plus a box of size 1 is a smarter start than a stockpile.
- Several packs, unscented for the early weeks when skin is most sensitive. Keep one pack in the changing bag.
- Diaper rash cream and a changing pad. A zinc-oxide cream handles most rashes; a wipeable changing pad saves endless laundry.
- Baby wash and shampoo. One gentle, fragrance-free product does both jobs for the first months. Not sure what all the label claims actually mean? Our guide to decoding modern baby shampoo claims breaks down paraben-free, sulfate-free, and tear-free in plain English.
- Baby bathtub or bath support. Newborns only need 2–3 baths a week, but a proper support makes those baths far less nerve-racking.
- Soft brush, baby nail clippers or file, and lotion. Newborn nails grow fast and scratch faces. A file feels safer than clippers for many new parents.
- Digital thermometer. A must from day one – any fever in a baby under 3 months needs a same-day call to the doctor. A rectal thermometer gives the most accurate reading at this age; forehead (temporal) models are the easiest for quick checks.
- Basic first-aid kit. Bandages, gauze, saline drops, and a bulb syringe or nasal aspirator for stuffy noses.
Safe Sleep
Sleep gear is where marketing and safety guidance clash the most, so here is the short version: babies sleep safest alone, on their back, on a firm flat mattress, with nothing else in the sleep space.
No pillows, no loose blankets, no bumpers, no weighted products.
That is the American Academy of Pediatrics safe sleep guidance, and it makes your shopping list shorter, not longer.
- Bassinet or crib. A bassinet is compact and lets baby sleep in your room for the recommended first 6 months; a crib lasts years. Many families use both – bassinet first, crib later. Buy a new mattress that fits snugly with no gaps; our Newton waterproof crib mattress review covers a breathable option we rate highly.
- Fitted sheets (2–3). That is all the bedding a baby needs. Nothing loose goes in the crib.
- Swaddles, then sleep sacks. Swaddling can calm newborns, but stop as soon as baby shows signs of rolling (often 2–3 months). From then on, a wearable sleep sack keeps baby warm with no loose fabric. Choose regular sleep sacks only – weighted swaddles and weighted blankets are not safe for infants.
- White noise machine (optional but loved). Masks household noise and mimics the womb. Keep it at a modest volume, placed well away from the crib.
- A dim, warm light makes night feeds and diaper changes easier without fully waking anyone.
- Baby monitor. Useful once baby sleeps in another room. An audio or basic video monitor is genuinely enough; smart monitors are a nice-to-have, not a need.
If sleep itself is the struggle rather than the gear, start with our guides on why your baby only sleeps when held and the 4 month sleep regression – the two sleep curveballs almost every parent meets in the first half year.
Feeding
Whether you are breastfeeding, bottle feeding, or combining both, the essentials are shorter than the store aisle suggests.
If you are breastfeeding
- Breast pump. Lets you build a stash, share feeds, and manage supply. In the US, check your insurance first – many plans cover a pump for free.
- Nursing pillow. Supports your arms and helps position baby for a better latch, which matters enormously in the early weeks.
- Nursing bras (2–3) and breast pads. Comfort and easy access, day and night.
- Milk storage bags. If you pump, you will need somewhere for that milk to go.
Worried about supply or your own diet while nursing?
See our guides to foods for breastfeeding mothers to eat and avoid and breastfeeding tips for producing more milk.
If you are bottle feeding (formula or pumped milk)
- Bottles and nipples (4–6 to start). Start with one brand in the smallest size and slowest flow; buy more only once you know baby accepts them.
- Bottle brush and drying rack. You will wash bottles constantly; make it easy.
- Any FDA-regulated infant formula is nutritionally complete – the right one is the one your baby tolerates and you can reliably find in stock.
For everyone
- Burp cloths (8–10). You will use more than you think. Plain cloth diapers work brilliantly for this.
- Essential once drooling ramps up around 3–4 months, and again when solids begin around 6 months.
- Pacifiers (2–3). Optional, but many babies love them – and pacifier use at sleep time is associated with a reduced risk of SIDS. Buy a couple of styles; babies have opinions.
Getting Out and About
- Infant car seat. The one item you cannot leave the hospital without, and the one place never to cut corners. Buy new (used seats can have invisible crash damage and expiry dates), check it fits your car, and install the base before your due date. Look for easy installation (ISOFIX/LATCH) and an adjustable harness.
- For the first 6 months you need one that reclines flat or accepts your infant car seat or a bassinet attachment. If you fly or travel often, a lightweight fold matters more than extra features – our roundup of the best lightweight, airline-approved travel strollers compares the top options.
- Baby carrier. Frees your hands and calms clingy newborns. Whichever style you choose, follow the TICKS rules: baby tight, in view, close enough to kiss, chin off chest, back supported.
- Changing bag. Any bag with pockets works – a dedicated one just makes the 47 small items easier to find.
Clothing (Without Over-Buying)
Newborn clothing is where most over-buying happens. Babies grow through sizes fast – some skip newborn size altogether – so buy a little of the current size and more of the next one up.
- Onesies / bodysuits (6–8 per size). The daily uniform. Envelope necklines and front snaps make changes (and blowouts) survivable.
- Sleepers with zips (4–6). Zips beat snaps at 3 a.m. Every experienced parent will tell you this.
- Socks or booties (4–6 pairs). They vanish constantly; buy one style in bulk so pairs always match.
- A soft hat for the early days, a warm one for winter, a brimmed one for sun.
- Seasonal layer. A cardigan or light jacket for cool days; a footmuff or snowsuit for cold climates. In the car seat, thick coats come off – bulky layers stop the harness from fitting safely.
- Swaddles and light blankets (2–3). For the stroller, the floor, and awake time – remember loose blankets stay out of the crib for sleep.

Play and Awake Time
Newborn ‘play’ is simple: faces, voices, and tummy time. Gear helps mostly by giving you somewhere safe to put the baby down.
- Play mat / play gym. The single best value item in this category – perfect for tummy time and batting at dangling toys from around 2–3 months.
- Bouncer seat. A safe spot for baby while you shower or cook. For awake time only – babies should not sleep in inclined seats.
- A few high-contrast toys and board books. Newborn vision is blurry and loves bold black-and-white patterns – here is what your newborn actually sees in the first week. Reading aloud counts from day one. For inexpensive options that punch above their price, see our best baby toys under $30.
- Baby swing (optional). A lifesaver for some fussy babies, ignored by others. Awake and supervised use only. If possible, try a friend’s before buying.
What You Can Skip (or Wait On)
Every item below is either unnecessary in the first 6 months, or actively not recommended:
- Weighted blankets, weighted swaddles, and weighted sleep sacks – not safe for infants, full stop.
- Crib bumpers – a suffocation risk; padded bumpers are banned from sale in the US.
- Shoes – pointless until walking. Socks and booties do everything shoes would.
- Wipe warmers, bottle sterilizer towers, diaper disposal systems – nice-to-haves at best. Hot soapy water and a lidded bin work fine.
- A high chair – you will want one around 6 months when solid foods begin, not before. The same goes for sippy cups and toddler plates.
- Newborn-size everything – buy small quantities of the smallest sizes and see how big your baby actually arrives.
Frequently Asked Questions
When should I start buying baby essentials?
Most parents start around the second trimester and aim to have the true essentials – car seat installed, somewhere safe to sleep, diapers, and a small clothing stash – ready by 36 weeks. Everything else can be bought after baby arrives, often with better information about what you actually need.
Do I need both a bassinet and a crib?
No – either works from birth as long as it meets current safety standards and has a firm, flat mattress. The AAP recommends room-sharing for at least the first 6 months, which is why many families start with a bassinet beside the bed and move to a crib later.
How many clothes does a newborn really need?
Per size: roughly 6–8 bodysuits, 4–6 sleepers, and 4–6 pairs of socks covers it, assuming you do laundry every couple of days. Babies outgrow sizes in weeks, so resist the adorable mountain of newborn-size outfits.
Is a video baby monitor necessary?
Not while baby sleeps in your room for the first 6 months. Once they move to their own room, a simple audio or video monitor is enough – no monitor is a medical device, and none replaces safe sleep practices.
The Bottom Line
A safe place to sleep, a correctly installed car seat, a way to feed, a stack of diapers, and a modest pile of clothes – that is genuinely the core of it.
Everything else on this list makes life easier, but the six-month version of you will be glad you spent on the essentials and skipped the clutter.
