Somewhere in the third trimester, the hospital bag jumps to the top of the to-do list. So when should it actually be ready — and what really needs to go in it?
The short version: be ready by 36 weeks
A full-term pregnancy can deliver anytime from 37 weeks, and early labour is always possible, so the standard advice is to have your bag packed and by the door by around 36 weeks. That gives you a comfortable buffer and means you’re never scrambling. Around 1 in 10 babies arrive before 37 weeks, so being ready a couple of weeks ahead is simply playing the odds sensibly — not being overly cautious.
If you’re in the thick of nesting around weeks 34–36, packing the bag is a satisfying, productive way to channel that energy. Think of 36 weeks as the deadline, not the start — gathering pieces gradually from around 32 weeks makes it feel effortless rather than like a last-minute dash.
When to pack earlier
Pack closer to 32 weeks if any of these apply:
- You’re expecting twins or more (multiples often arrive earlier).
- You have a history of preterm labour or early birth.
- Your provider has mentioned a condition that raises the chance of an early delivery.
- You live far from the hospital and want extra peace of mind.
When in doubt, ask your midwife or doctor what timing makes sense for you. Here’s a quick guide:
| Your situation | Aim to be packed by |
|---|---|
| Straightforward single pregnancy | ~36 weeks |
| Expecting twins or more | ~32 weeks |
| History of preterm or early birth | ~32 weeks |
| Far from the hospital | A little earlier, for peace of mind |
What if you have a scheduled C-section or induction?
If your birth is booked for a specific date, you have a luxury most people don’t: you know roughly when to be ready. Even so, pack at least a few days before the date — inductions and planned caesareans can be brought forward, and labour can always start on its own beforehand. Pack as if you’ll stay a little longer too, since a planned caesarean often means a 2–4 night stay rather than one.
So a booked date doesn’t replace the 36-week rule — it sits alongside it. Be broadly ready by 36 weeks, then do a final top-up (fresh snacks, chargers, last-minute toiletries) in the day or two before you’re due in.
How to know it’s time to go (not just time to pack)
Packing early is about preparation; knowing the signs of labour is about timing. Head in — or call your provider — if you notice:
- Regular, strengthening contractions that get closer together and don’t ease when you move or rest.
- Your waters breaking — a gush or a steady trickle of fluid.
- Any bleeding, or a noticeable drop in your baby’s movements.
Always follow your provider’s specific guidance on when to come in, and don’t hesitate to call if something doesn’t feel right — that’s exactly what they’re there for. (If you’re unsure how far along you are, our Pregnancy Week Tracker shows your current week at a glance.)
What if labour starts before you’ve packed?
First, don’t panic — early labour usually builds over hours, not minutes, especially with a first baby. Keep a short “grab list” stuck to the fridge or in your phone so anyone can finish the job fast: ID, phone and charger, a going-home outfit for you and baby, and the car seat. Everything else is a nice-to-have. The single thing you truly can’t leave without is a properly installed infant car seat, so fit and check that well ahead of time.
What actually goes in the bag
You need far less than the internet suggests. The essentials fall into four groups:
- For you: comfortable nightwear, non-slip socks, toiletries, going-home outfit, glasses.
- For baby: a couple of onesies, a hat, a swaddle, and a going-home outfit.
- Documents & tech: photo ID, health/insurance card, phone + long charger.
- The non-negotiable: a properly installed infant car seat — most hospitals won’t let you leave without one.

Should you keep anything in the car?
It’s worth getting the car seat installed and checked from around 35–36 weeks, rather than leaving it as a job for the day itself — fitting one for the first time under pressure is no fun. Some people also tuck a small backup into the car: a spare phone charger, a bottle of water and a light snack, so even an unplanned dash isn’t completely bare. Keep the main bag in the house by the door, though — you don’t want your essentials sitting in a hot or freezing car for weeks.
A calm final tip
Keep the packed bag somewhere obvious and tell your partner exactly where it is. Babies have a habit of arriving at inconvenient moments — and “it’s by the door, ready to go” is a wonderful thing to be able to say at 3 a.m.
