Nappy bag essentials

One thing nobody really prepares you for is how quickly a nappy bag turns into carrying your entire house around.

I used to think I needed absolutely everything “just in case”, but realistically, there are a few things you reach for constantly when you’re out with a baby.

This is the setup that actually makes sense for me — practical, easy to carry, and enough to survive feeds, changes, spills, and longer days out without panicking halfway through.

Feeding essentials

When you’re out with a baby, feeding is usually the thing you need to plan around most.

Whether you’re using formula, breast milk, or doing a mix of both, having everything ready beforehand makes leaving the house so much easier.

I always make sure I have:

  • a portable bottle warmer

  • bottles

  • breast milk

  • formula portions

  • a flask with hot water

  • muslin cloths for spills and feeds

If you’re breastfeeding or pumping while out, it also helps to think about how you’ll store milk properly if you’re going to be away longer.

You can also read my Breastfeeding Basics guide if feeding feels overwhelming at first, or my Breastfeeding Equipment Explained guide for pumps, storage, and feeding equipment.

This is the category that somehow fills the bag the fastest.

The main thing I’ve learned is that you don’t need loads of random extras — you just need the things you’ll realistically use often.

For me that’s:

  • nappies

  • wipes

  • changing mat

  • nappy cream

  • hand sanitiser

  • antibacterial wipes

  • nappy bags

  • one spare outfit

The spare outfit is one of those things that feels unnecessary until you suddenly really need it.

I also always keep wipes easy to reach because somehow everything gets sticky the second you leave the house.

My Preparing for a Baby guide and Hospital Bag Essentials post both go into the things that are genuinely useful vs the things people massively overbuy.

What helps: Products I actually used

For longer days out

Short trips are one thing. Longer days out are where you suddenly realise what’s actually useful.

If I know I’ll be out for hours, I usually bring:

  • extra milk or formula

  • an extra bottle

  • a breast pump

  • an insulated cooler bag

That setup is especially useful if you’re pumping while out or need to keep milk cold properly during travel.

Final thought

You honestly don’t need to pack your entire house every time you leave with a baby.

Most of the time, having a small setup that’s practical and easy to grab quickly is much more useful than carrying loads of “just in case” items you never touch.

This isn’t professional advice — just a simple breakdown of what I’ve found helpful.

Most of this is easier to understand visually.

FAQs

What should always be in a nappy bag?

The basics I always reach for are nappies, wipes, bottles, milk or formula, a spare outfit, muslin cloths, and hand sanitiser. Once you’ve been out with a baby a few times, you realise you don’t actually need half the random extras people suggest.

How many nappies should I pack for a day out?

I usually pack more than I think I’ll need, especially for longer trips. A few spare nappies takes up less space than dealing with a surprise blowout with no backup.

Do I need a portable bottle warmer?

Not always, but I do think they make longer trips much easier. Especially if your baby prefers warm bottles and you’re away from home for a while.

What’s the best way to carry breast milk when out?

An insulated cooler bag makes the biggest difference for longer days out. It keeps bottles, milk, and even pumps all in one place instead of everything floating around separately in your bag.

Is the Nuby RapidCool worth it?

If you formula feed regularly while out, honestly, probably yes. It makes making bottles away from home much quicker and less stressful, especially when your baby suddenly decides they’re starving immediately.

How do I stop overpacking my nappy bag?

I started asking myself what I actually use every single outing instead of packing for every possible scenario. Once you do that, the bag gets much lighter very quickly.
