When to Buy Baby Clothes During Pregnancy
One of the most exciting parts of expecting a baby is imagining those tiny outfits — but knowing when to buy baby clothes during pregnancy can save you money, wardrobe space, and a fair amount of stress. It is tempting to fill a basket with adorable pieces the moment you see two lines on the test, yet a little patience and planning go a long way. In this trimester-by-trimester guide we will walk you through the smartest shopping timeline so you end up with exactly what your newborn needs — and nothing gathering dust at the back of a drawer.
First Trimester: Browse, Research and Set a Budget
During the first twelve weeks most parents-to-be are still keeping the news close to their chests, and that is perfectly fine when it comes to shopping too. This is your research phase rather than your spending phase. Use the time to explore brands, fabrics and styles so you can make confident choices later on.
Why Fabric Matters From the Start
GOTS-certified organic cotton should sit at the top of your checklist. A newborn's skin is up to five times thinner than adult skin, which means it absorbs chemicals far more readily. Conventional cotton is one of the most pesticide-heavy crops in the world, so choosing GOTS-certified organic cotton ensures the fabric has been grown, processed and dyed to the strictest environmental and social standards. At Sleep No More every piece is made from this very cotton — soft against delicate skin and kinder to the planet.
Create a Wish List, Not a Shopping Cart
Bookmark your favourites rather than buying them straight away. You do not yet know the season your baby will arrive in, whether friends and family plan to gift clothing, or how many items you will receive at a baby shower. A curated wish list — especially one filled with organic bodysuits in versatile prints — keeps your excitement alive without the risk of over-buying.
Second Trimester: Start Shopping Strategically
The second trimester — weeks 13 to 27 — is widely considered the sweet spot for baby-clothes shopping. Energy levels tend to pick up, the 20-week scan gives you a clearer picture, and there is still plenty of time to spread the cost.
Focus on Newborn Essentials First
Bodysuits are the backbone of any newborn wardrobe. Most midwives and experienced parents agree that you need around six to eight bodysuits in newborn and 0–3 month sizes. Choose a mix of long-sleeve and short-sleeve styles so you are covered regardless of the weather. Gender-neutral designs — think bold original prints, playful illustrations and nature-inspired motifs — are a smart move because they work for any baby and can be passed on to siblings or friends.
Layer up with a few key extras. Two or three sleepsuits, a couple of hats, a lightweight cardigan and a set of scratch mittens round out the essentials. Resist the urge to buy mountains of clothing in the smallest size; newborns grow astonishingly fast, and some babies skip the newborn size altogether.
Consider Bundles to Save Time and Money
Curated bundles take the guesswork out of building a capsule wardrobe. Sleep No More's organic bundles pair bestselling bodysuits together at a gentle saving, so you get coordinated pieces without duplicating what you already have. Bundles also make a thoughtful gift-registry suggestion if loved ones ask what to buy.
Third Trimester: Fill the Gaps and Get Organised
By the time you reach the third trimester your hospital bag is on your mind, and so is the question of whether you have bought enough — or too much. This final stretch is about filling genuine gaps rather than panic-buying.
Audit What You Have
Lay everything out and take stock. Sort by size, count how many bodysuits, sleepsuits and layers you own, and check whether the seasonal balance is right. A baby due in October in London will need warmer layers than one arriving in June, so adjust accordingly. If you spot a gap — perhaps you are short on long-sleeve bodysuits — a quick visit to the new-in collection will help you find the freshest organic styles.
Wash, Fold and Pack
Pre-wash all clothing before baby arrives. Even GOTS-certified organic cotton benefits from a gentle 30-degree wash to soften the fibres and remove any warehouse dust. Use a fragrance-free, baby-safe detergent and skip the fabric conditioner. Once everything is dry, fold items by size so you can grab the right outfit at three in the morning without switching on every light in the house.
Resist the Urge to Size Up Too Early
Buying too far ahead is one of the most common mistakes. It is nearly impossible to predict your baby's growth rate or the season they will be wearing 6–9 month clothing. Stock up on newborn and 0–3 month sizes now, and save larger sizes for later when you have a better sense of your little one's build and the weather ahead.
Frequently Asked Questions
How many baby clothes do I actually need before the birth?
For the first few weeks you will want around six to eight bodysuits, three to four sleepsuits, two hats, a cardigan and a pack of scratch mittens — all in newborn or 0–3 month sizes. That may sound modest, but newborns spend most of their time sleeping, feeding and being cuddled, so a compact capsule wardrobe that you wash every couple of days is far more practical than an overflowing chest of drawers.
Is it bad luck to buy baby clothes too early in pregnancy?
This is entirely a personal and cultural decision. Some families prefer to wait until after the first scan or even until the third trimester, while others start browsing straight away. From a practical standpoint there is no downside to buying early as long as you keep receipts and choose styles in standard sizes. If you would rather wait, bookmarking your favourites and sharing a wish list is a lovely middle ground.
Why should I choose organic cotton for my newborn?
Newborn skin is incredibly sensitive and absorbs substances more easily than adult skin. GOTS-certified organic cotton is grown without synthetic pesticides or fertilisers and processed without harsh chemicals, making it one of the safest fabric choices for your baby. It is also softer, more breathable and better for the environment — a win on every level.
Should I buy gender-neutral baby clothes?
Gender-neutral designs are a brilliant choice for several reasons. They work whether you find out the sex beforehand or keep it a surprise, they can be handed down to future siblings regardless of gender, and they tend to feature more creative, original prints rather than relying on tired stereotypes. Sleep No More's collections are designed with exactly this philosophy — bold, playful and made for every baby.
What is the best way to avoid over-buying baby clothes?
Start with a clear essentials checklist and stick to it during the second trimester. Wait to see what gifts arrive before topping up, and avoid buying beyond the 0–3 month size until your baby is here and you can gauge their growth. Choosing versatile pieces — like organic bodysuits with mix-and-match prints — means fewer items that work harder.
