Changing Bag Checklist: What to Pack and What to Skip
You've got the bag. It weighs more than the baby. And somewhere between the car park and the second coffee, you find out that the one thing you needed wasn't in it.
That's the real problem with a changing bag. Not which one to buy – what goes in it, and how it stays stocked. So here's the list I settled on after a year of overpacking, the feeding bit most checklists skip entirely, and the things I stopped carrying altogether.
The short answer: nappies for twice as long as you think you'll be out, wipes, a fold-up mat, barrier cream, nappy sacks, two spare sets of clothes, two muslins and something to put the wet things in. Everything else is optional, including the changing bag itself.
Do you actually need a changing bag?
No. You need a bag. Whether it's a changing bag is up to you.
What a proper one buys you is worth knowing, though, because it isn't nothing: an insulated bottle pocket, a mat that folds into its own pouch, clips for the pram handles, and pockets shallow enough that you can find a nappy one-handed in a dark room. If you've already got a rucksack you like and a mat that rolls up, you have a changing bag and you've saved yourself sixty quid.
The one thing I'd push back on is a lovely bag with a single enormous compartment. Everything sinks, and you end up emptying it onto a baby-change table to find the wipes.
What actually earns its place
The NHS list for a nappy change itself is short: a mat or towel, cotton wool and warm water or gentle, non-scented, alcohol-free wipes, something to put the dirty nappy in, barrier cream, a clean nappy, and clean clothes. Everything else below is on my list because I got caught out without it.
The changing bag checklist
- Nappies, and the next section covers how many
- Nappy sacks, or any small bag that ties shut
- Wipes. Non-scented and alcohol-free while they're tiny, which is the NHS line
- A fold-up changing mat. The pub floor is the pub floor
- Barrier cream, in a small pot rather than the family-sized tube
- Two spare sets of clothes. Not one
- Two muslins. One for them, one for your shoulder
- A carrier bag for whatever comes off and can't go back on
- Hand sanitiser, for you
- A snack and a water bottle, also for you. You will forget this and you will regret it
Ticks won't survive a page reload, so work down it as you pack.
How many nappies, and how many spare sets?
More than you'd guess, is the honest answer. The NHS puts it at around 10 to 12 nappy changes a day in the first weeks, settling to six to eight once they're a bit bigger.
My rule, which is mine rather than anyone official's: one nappy for every two hours you'll be out, plus two. Three hours at a soft play is five nappies. It sounds like too many right up until the afternoon it isn't.
Two spare sets rather than one, and the reason is dull. The first change happens. Then, forty minutes later, the second one happens, and you are in a supermarket car park with a bare baby and a lot of decisions to make. If you drive, keep a third set in the car and forget about it until you need it.
If you're the person buying for someone rather than the person packing, that's the useful gift hiding in all of this. Not another newborn sleepsuit – muslins, bibs and a spare set in 3–6 months, which is roughly when the drawers go bare and the visitors have stopped coming. I've gone into why that size wins in what size baby clothes to buy as a gift.
The Nursery Collection
Two cotton muslins, a fleece wrap and a character comforter. The muslins are the bit that lives in the bag and gets used daily. The comforter is for the pram, the sofa and being carried about by one ear, not for the cot.

Feeding away from home, without the panic
This is the section most changing bag lists leave out, and it's the one that generates the most standing-about-in-a-car-park stress.
If you're breastfeeding, you need nothing you haven't already got, plus whatever makes you comfortable – a muslin, a drink, and somewhere to sit that isn't a bench in the rain.
If you're formula feeding, the guidance is more specific than most people realise, and much better known before you're out than after. The NHS points parents to the NCT for this, and the NCT set out three routes:
- A vacuum flask of water that's just been boiled, carried alongside the measured powder in a clean sealed container and a sterilised bottle with the cap on. The NCT note that a full flask stays above 70°C for up to about three hours – less water cools faster, so around two hours for 285ml and about an hour for 145ml.
- A feed made up at home, cooled, then carried in a cool bag with an ice pack and used within four hours.
- Ready-to-feed liquid formula, which the NCT say is the NHS recommendation where making up a fresh feed away from home isn't possible.
All three are legitimate. Pick whichever fits the day.
Where to get help
If you're unsure which of these suits your baby, or feeding is going badly in a way that's wearing you down, your health visitor or midwife has had this conversation hundreds of times. The National Breastfeeding Helpline is on 0300 100 0212, and there's feeding guidance on nhs.uk.
Where do you actually change them?
The bag is only half the problem. The other half is that the baby-change room is on the wrong floor, occupied, or simply not there.
| Where | Good for | Watch out for |
|---|---|---|
| Shopping-centre baby change | A proper table, a bin, somewhere to put the bag down | Often one room per floor, so there's a queue at eleven o'clock |
| Café or pub loo | Usually fine if you've brought your own mat | No table, so it's a floor change. This is what the mat is for |
| Back seat or boot of the car | Private, no queue, no audience | Rain, and you'll want everything within one arm's reach |
| Someone's house | Easiest of the lot | Ask first, and put your own mat down on their carpet |
One thing the NHS is blunt about, wherever you are: if you're using a changing table, stay with your baby the whole time and never turn your back or walk away. The floor is less glamorous and you can't fall off it.
What I stopped carrying
This is the half of the list nobody writes.
- The organiser inserts. Pockets you can't see into are worse than one space you can.
- A full tub of wipes. Decant into a travel pack and refill it at home.
- Three toys. One, and it will lose to a receipt from your coat pocket.
- A bottle warmer. Nothing in a changing bag should need mains electricity.
- Newborn-size spares, once they're past newborn. Everybody forgets this one. Check the spare sets every few weeks or you'll be holding up a vest that fits a doll.
The one I'll hedge on is a spare top for yourself. I carried one for eight months and used it once. If your baby is reliably sicky, carry it and ignore me.
Bella's tip
Restock the bag when you walk through the door, not when you're leaving. It takes two minutes while the kettle boils, and it is the only reason I ever stopped getting caught out.
Questions people ask
What should I put in a changing bag for a newborn?
Nappies, nappy sacks, non-scented alcohol-free wipes, a fold-up changing mat, barrier cream, two spare sets of clothes, two muslins and a carrier bag for wet things. The NHS list for the change itself is a mat, cotton wool and warm water or gentle wipes, somewhere for the dirty nappy, barrier cream, a clean nappy and clean clothes.
How many nappies should I take out with me?
A useful rule of thumb is one nappy for every two hours you expect to be out, plus two spares. For context, the NHS says newborns need changing around 10 to 12 times a day in the early weeks, dropping to six to eight times a day as they get older, so a long day out can easily run through four or five.
Can I take a made-up bottle of formula out with me?
Yes, with conditions. The NCT, whose guidance the NHS points parents to for feeding away from home, say a feed made up at home should be cooled, carried in a cool bag with an ice pack, and used within four hours. The alternatives are a vacuum flask of just-boiled water with measured powder carried separately, or ready-to-feed liquid formula.
Do I need a proper changing bag, or will any bag do?
Any bag will do. A dedicated changing bag adds an insulated bottle pocket, a fold-out mat, pram clips and shallow pockets you can search one-handed, which are genuinely useful rather than essential. A rucksack you already own plus a separate roll-up mat does the same job for nothing.
You will still get caught out, and it will be by something not on any list. Two spare sets and a mat in the bag is the difference between that being a nuisance and a disaster, and that's as good as it gets.
If you're pulling a present together for someone about to start all this, the practical end of the range beats the decorative one.
And if you want the full version of what to buy before the baby arrives, it's in the newborn essentials checklist.
What's the one thing in your changing bag you'd tell everyone to carry? Mine is the second set of clothes. Tell me in the comments – I read all of them, though they're checked before they appear, so don't worry if yours takes a day. Or come and say it on Instagram.
