Bringing home a new baby comes with equal parts joy, exhaustion, and āwhat on earth do I actually need to buy?ā One of the most common questions new parents ask, sometimes while staring at a computer screen in the middle of the night with glazed eyes, is: What clothes does a newborn actually wear?
If youāve already googled āhow many newborn clothes do I need,ā youāve probably landed on a dozen lists that look more like shopping sprees than realistic plans. Thatās why we made this guide: to cut the noise and tell you what actually matters, why it matters, and how not to drown in onesies youāll never use. Think of it as your babyās layette (thatās the fancy name for a first wardrobe), updated for people who donāt have time for fluff.
The Baby Clothes Checklist (0ā3 Months)
The first three months are basically laundry Olympics. You donāt need a boutique rack of outfits; what you do need is a core set of workhorse pieces that can handle spit-up, blowouts, and āoops, we already outgrew thatā moments. And the items you need, need to be high quality.
Sleepers: The All-Day, All-Night Uniform
Sleepers are the real MVPs. Your baby can nap in them, āgo outā in them (translation: the pediatricianās office), and live in them without judgment. Easy snaps are your best friend at 3 a.m. when your baby has transformed into a wiggle worm.
How many: 5ā7
Bodysuits (Onesies): The Cornerstone
If sleepers are the MVP, bodysuits are the offensive line. They snap at the bottom, making diaper changes less of a strip show. They layer under everything, and in hot weather, they are the outfit. Stock both short- and long-sleeved versions. Short-sleeve bodysuits for summer or layering, long-sleeve bodysuits for cooler rooms and outings.
How many: 6ā8 (half and half long to short sleeve)
Baby Hats: Small but Mighty
Babies are basically heat-leaking machines. Hats keep them warm when itās chilly, but skip them for sleep (overheating is a real risk).
How many: 2ā3
Blankets: Multipurpose Magic
Organic cotton blankets do it all: swaddling, stroller shade, nursing cover. Just keep it breathable and soft.
How many: 2ā3
Burp Cloths: Because Spit-Up Happens
Youāll need burp cloths more than you want to admit. They save your clothes, your babyās clothes, and your couch.
Your babyās skin is thinner, more sensitive, and basically allergic to nonsense. Fabrics treated with flame retardants, wrinkle-free finishes, or azo dyes can irritate or worse. Natural fibers like organic cotton or linen are softer, safer, and breathable. Certifications like GOTS or OEKO-TEX are your shorthand for ānot secretly toxic.ā
Zippers: Fast, efficient, and a gift when youāre half-asleep. A two-way zipper makes diaper changes quicker than you thought humanly possible. The catch? They can snag delicate newborn skin, which is why we donāt use them.
Snaps: Slightly less glamorous, but safer. Yes, lining up ten snaps at 2 a.m. feels like a puzzle you didnāt sign up for, but theyāll never pinch your babyās skin or jam halfway through. Ours are nickel-free, easy to snap as they are color-coded, and built for durability, so you get the safety without the headache.
Our vote? Keep a mix!
Dressing for the Weather (Without Guesswork)
Babies canāt regulate temperature well. Translation: itās on you.
Rule of thumb: One more layer than youāre wearing.
Hot weather: Stick to a cotton bodysuit or just a diaper indoors. Add a hat outdoors. Skip sunscreen under 6 months.
Cold weather: Layer. Bodysuit, sweater, then outerwear. Always wear a hat outdoors.
Nighttime:Donāt overheat. Use sleep sacks, not loose blankets. Baby should feel warm, not sweaty. No hats in bed.
Laundry: The Hidden Full-Time Job
Baby laundry is relentless. Hereās how to cope:
Wash everything before first wear.
Use fragrance-free detergent.
Skip fabric softeners.
Wash small, frequent loads.
Sunlight is your friend; it fades stains and disinfects.
The Final Checklist (No Frills)
So here it is. The actual newborn clothes checklist that wonāt waste your money or your closet space:
5ā7 sleepers
6ā8 bodysuits
2ā3 hats
2ā3 blankets
3-5 burp cloths
Add socks and a sweater depending on your climate, and youāre done. No baby needs a full designer wardrobe. What they need is safe, comfortable, breathable clothing, and what you need is one less thing to stress about.
At Treehouse, we design with that in mind: fewer, better pieces that work hard so you donāt have to. As always, let us know if you ever need help or have any questions. Weāre here to make this easier!
