A well-packed diaper bag holds about one diaper for every 2 hours you’ll be out, plus 2 extra; wipes and a changing pad; feeding supplies; one or two spare outfits; and a small health kit. The exact list changes as your baby grows. Newborns need more diapers and burp cloths, while toddlers need snacks, a cup and something to keep them busy. Restock as soon as you get home, so the bag is always ready to go.
Key takeaways
- Pack diapers for the time you’ll be out, plus 2 spares.
- Always carry a spare outfit for your baby, and a spare top for you.
- Keep pumped milk cold in an insulated bag with ice packs.
- Never drape a blanket over the stroller; it traps heat.
- Restock after every outing.

By age
Newborn (0–3 months)
- Extra diapers: newborns use 10–12 a day. Our diaper calculator estimates how many by age.
- 3–4 burp cloths, and a muslin for spit-up
- Two spare outfits, since blowouts happen
- A swaddle or sleep sack if you’ll be out at nap time
Baby (4–12 months)
- Pouches or a small container of soft finger foods, a spoon and a bib
- A cup for practising water sips with meals
- Teething toy, and a toy clip so it doesn’t hit the floor
- Sun protection: keep babies under 6 months in the shade. For older babies, use a sun hat and baby-safe sunscreen.
Toddler (1–3 years)
- Fewer diapers, or training pants plus spare underwear if potty training
- Snacks and a water bottle
- A small activity: stickers, a board book or a small car
- A comfort object if they have one
Packing pumped milk
Freshly pumped milk keeps up to 4 hours at room temperature. To carry it longer, use an insulated cooler bag with frozen ice packs, and use it within 24 hours or move it to a fridge. Our breast milk storage calculator gives the exact use-by time.
Choosing a diaper bag
- Backpack: hands-free and spreads the weight. The most popular choice for good reason.
- Tote or messenger: easy to reach into, but it sits on one shoulder.
- Stroller organizer: fine for short walks. Don’t hang heavy bags on stroller handles, which can tip the stroller.
Look for wipe-clean lining, an insulated bottle pocket, a separate wet pocket, a built-in changing pad and stroller straps.
Handy for days out and trips
- Keep medicines, sanitizer and small items in a zipped pocket out of your child’s reach.
- Never cover the stroller with a blanket or muslin. It can trap heat dangerously, even in mild weather.
- Don’t leave a baby in a car, even for a minute.
Frequently asked questions
How many diapers should I pack?
One for every 2 hours you’ll be out, plus 2 extra. For a 4-hour outing with a newborn, that’s 4 diapers.
Do I need a “diaper bag”, or will any bag do?
Any bag works. Dedicated diaper bags just add useful pockets, a changing pad and insulated bottle sleeves.
What’s the first thing people forget?
A spare top for themselves, and restocking the diapers after the last outing.
