Packing too early means repacking when things change; packing too late means doing it between contractions. What follows is the version that survives both — organised by who each item is actually for.
This is the one item that's a legal requirement, not just a nice-to-have — by UK law, a newborn must travel in an appropriate car seat from their very first journey, and many maternity units won't discharge you without seeing one. An infant car seat like the iCandy Cocoon 360, at £199, rated from birth, is the one to bring to the hospital, not leave in the car park for someone to fetch later.
Fit the car seat in your actual car and practise before you go into labour — working out how it clicks into the ISOFIX base for the first time in a hospital car park is not the moment for it.
Pack one going-home outfit sized for a newborn, plus a backup in the next size up — some babies arrive bigger than expected. A sleep bag like ergoPouch's Organic Long Sleeved Sleepsuit Bag, at £74.95, or a fitted swaddle such as the Love To Dream Swaddle Up Newborn, at £38, both work for the trip home and the first nights.
Bring two sizes of going-home outfit, not one — a newborn-size outfit on a bigger-than-average baby is a genuinely common reason parents end up buying something from the hospital shop.
Pack more nappies than feels necessary — newborns go through them fast, and you don't want a midnight trip to the hospital shop. A couple of organic cotton muslins, at £35 for a set of two, cover everything from mess to swaddling to shade.
Muslins get used for far more than their name suggests — burping, wiping, a makeshift blanket — pack more than you think you need.
If you intend to offer a dummy, bring it — hospitals generally won't provide one, and it's easier to have your own on hand than to decide in the moment. An Avery Row Pacifier Holder, at £9, also keeps it from ending up lost in hospital bedding.
Skip this entirely if you haven't decided on dummy use yet — it's genuinely one of the few items here that's fine to add later once you know.
This is the one section with no catalog product behind it, and that's fine — maternity pads, old or dark-coloured underwear, and loose, comfortable clothing for the stay and the journey home are the practical basics. Pack more pads than you think you'll need; this isn't an area to run short on.
Pack clothes you don't mind never wearing again — the days immediately after birth are not the time to worry about a favourite top.
Hospital chairs aren't built for feeding comfort. An Avery Row Nursing Pillow, at £54, supports both positioning and your own back during the early feeds, whether you're in a hospital bed or a chair.
A nursing pillow earns its place in the bag even for a short hospital stay — the first feeds are often the hardest to get positioned correctly, and support helps.
A structured bag that separates your things from the baby's makes a genuine difference when you're exhausted and looking for a specific item. Avery Row's Baby Changing Bag Bundle, at £115, comes with a built-in changing mat, which doubles as something useful once you're home.
Pack the bag as two sections, not one pile — yours and the baby's — so whoever's searching it at 3am doesn't need to dig through everything.
Another section with nothing to link, deliberately — a birth partner's bag is personal: phone charger, snacks that don't need a fridge, a few pounds in cash for the car park or vending machine, and a change of clothes for a stay that might run longer than planned.
Pack the birth partner's bag with the same seriousness as the others — a long labour with no snacks and a dead phone helps no one.
Hospitals vary in whether they stock formula, and early feeding doesn't always go to plan in the first hours. A small pack of Tommee Tippee's Natural Start Anti-Colic bottles, from £15.99, is a sensible backup to have, not a signal you've decided against breastfeeding.
Having a backup doesn't mean you'll need it — it means not scrambling to find one at 2am if the first feeds are harder than expected.
FAQ
When should I actually pack the hospital bag?
By around 36 weeks is the usual guidance, since labour can start before your due date. Pack it, then leave it somewhere you won't have to search for it.
Do I need two sizes of going-home outfit for the baby?
Yes — pack a newborn size and the next size up. Bigger-than-expected babies are common enough that this is worth the extra five minutes of packing.
What's genuinely optional in this list?
The dummy and holder, if you haven't decided on dummy use, and the backup bottles, if you're confident about how early breastfeeding is going. Everything else — the car seat, going-home outfit, nappies and nursing pillow — covers something that's hard to improvise at the last minute.
Does the car seat actually need to come into the hospital with us?
It's worth bringing, or at minimum having fitted and ready in the car — many maternity units check it's correctly fitted before discharge, and you don't want that check happening for the first time in the car park.
