When to Buy Baby Gear: A Trimester-by-Trimester Shopping Timeline

There is a moment in every pregnancy where you open a browser tab labelled "things to buy for baby" and immediately close it again because the list is absolutely terrifying. Pushchairs, car seats, cots, monitors, muslins, bottles, a mysterious item called a "Sleepyhead" that costs more than your first car. The sheer volume of Stuff is enough to make anyone hide under the duvet and pretend their due date is a distant rumour.

Here is the good news: you do not need to buy everything at once. In fact, buying everything at once is one of the most common pregnancy regrets. You end up with a mountain of packaging in the spare room, a credit card that needs a lie-down, and at least three things you will never use. The smarter move is to spread it out across your pregnancy, buying the right things at the right time.

This is that timeline.

First Trimester: Research, Not Receipts (Weeks 1-13)

Your first trimester is for dreaming, not spending. You are tired, possibly nauseous, and probably keeping things quiet for a little while longer. This is not the time to walk into a baby shop and hand over your debit card.

What it IS the time for is research. Start a running list on your phone. Every time someone mentions a product they loved, add it. Every time you see a recommendation online, note it down. You are building a shortlist, not a shopping basket.

The only purchase worth making this early? Something for YOU. A decent pregnancy pillow can make the difference between sleeping and staring at the ceiling from about week 10 onwards, and it only becomes more essential as the bump grows. It is one of those things people wish they had bought sooner.

Beyond that, your money stays in your pocket. Resist the urge to impulse-buy tiny socks. They are adorable, but your baby will kick them off within thirty seconds of being born and you will find them wedged behind the sofa six months later.

Second Trimester: The Big Decisions (Weeks 14-27)

This is the golden window. You have (hopefully) got your energy back, the bump is visible enough that shopping feels real, and you have enough time to research properly, order sensibly, and wait for sales without panicking about delivery dates.

The second trimester is when you tackle the big-ticket items. These are the purchases that take the most thought, cost the most money, and have the longest lead times if something needs ordering in.

Your pushchair or travel system

This is probably the single biggest baby purchase you will make, and it deserves proper thought. Go to a shop and push a few around. Fold them. Put them in your car boot. Check whether they fit through your front door. Online reviews are helpful, but nothing beats physically wrestling with a chassis in a John Lewis aisle to know whether it is The One.

If you are leaning towards a travel system (pushchair, carrycot, and car seat that all click together), ordering around weeks 20-24 gives you plenty of breathing room. Most UK retailers deliver within two weeks, but popular colourways sell out during peak season.

The sleep setup

Whether you are going for a bedside crib, a moses basket, or a full cot, the second trimester is when to decide. Your midwife will talk to you about safe sleep guidelines at your 20-week appointment, and that conversation usually helps narrow things down.

A bedside crib is the most popular first sleep space in the UK right now, and for good reason. It sits level with your bed, lets you reach your baby without getting up, and most convert to a standalone crib when you are ready to transition.

The car seat

You cannot bring your baby home from hospital without one. If you have bought a travel system, the infant car seat is usually included. If not, now is the time to choose. Make sure it fits your car before you buy, as not every seat works with every vehicle. Most retailers will do a free fitting check.

Nursery furniture

If you are setting up a nursery, the second trimester is the sweet spot. You have energy for painting walls and building flat-pack furniture, and you are not yet at the stage where bending over to tighten a bolt feels like an Olympic sport. A chest of drawers with a changing top, a chair for feeding, and some storage baskets will cover most of what you need.

Third Trimester: The Finishing Touches (Weeks 28-40)

By the third trimester, the big stuff should be sorted. What is left is the smaller, more fun shopping, the bits and pieces that turn a room full of furniture into an actual space ready for a baby.

Muslins (buy more than you think)

Everyone says this and everyone is right. Muslins are used for burping, mopping, swaddling, draping over the pushchair as a sun shade, and approximately forty-seven other things you cannot predict yet. A pack of four is a starting point. You will want eight to ten.

Sleep bags and swaddles

Now that you know your due date and the season your baby will arrive in, you can choose the right tog. A summer baby needs a lighter weight than a winter one. Most parents start with swaddles for the newborn weeks, then move to sleeping bags from around eight weeks or whenever their baby starts wriggling free.

Bottles and feeding gear

Even if you are planning to breastfeed, having a couple of bottles in the house is sensible. You might want your partner to do an occasional feed, or you might express milk. There is no need to buy a full set of twelve, though. Start with two or three and see which brand your baby takes to, because they are surprisingly fussy about teat shapes.

Nappies and wipes

Stock up from about week 34. Newborn sizes are used for a surprisingly short time (some babies skip them entirely), so do not go overboard. Two packs of newborn, two packs of size one, and a big box of water wipes is a sensible starting stash. You will burn through them faster than you think, but supermarkets are open seven days a week and delivery apps exist for a reason.

The changing bag

Pack it by week 36 so it is ready to grab. Most parents overthink this purchase. You need something with enough pockets, a changing mat, and a size that does not make you feel like you are going on a two-week holiday every time you pop to the coffee shop.

What Can Wait Until After Baby Arrives

There are things you genuinely do not need until your baby is here, and buying them too early is a waste of money or space (or both).

• A high chair. Not needed until around six months when weaning starts. Save the kitchen space.
• Toys. Newborns are interested in exactly three things: milk, sleep, and your face. A rattle or two is fine, but the activity gym can wait a few weeks.
• Bigger clothing sizes. People will gift you newborn outfits. Buy ahead only if you spot a sale, and even then stick to basics in 3-6 month sizes.
• A baby carrier. Worth trying on before you buy, and your body shape will be different postpartum. Many sling libraries let you borrow and test before committing.
• A full sterilising setup. See what feeding method you land on first. A microwave steriliser bag costs a couple of pounds and does the job until you know whether you need the full electric unit.

The Secret Nobody Mentions

Here is the thing about baby shopping that nobody tells you: half of the best gear recommendations come AFTER the baby is born, from other parents you meet in baby groups, from your health visitor, from the mum at the coffee shop who swears by a particular brand of sleeping bag. You cannot research your way to a perfect list before birth because you do not yet know your baby or your own parenting style.

So buy what you need, when you need it, and give yourself permission to figure the rest out as you go. Your baby does not care whether the nursery is Instagram-ready. They care that you are there, that they are warm, and that milk appears at regular intervals. Everything else is a bonus.

If you want to keep track of everything in one place, a BubsNest registry lets you build your list gradually, share it with family, and tick things off as they arrive. No spreadsheets, no group chats asking "has anyone bought the cot yet?", just a calm, organised way to get ready. 🛒
