Everyone over-packs the first one. You take a bag the size of a weekend case, and you come home having used two things and carried the other nineteen around a park.
The correction is not to pack less. It's to pack for the two things that genuinely go wrong.
The two failure modes
A change goes badly. Not the change itself — the aftermath. This is what most of the bag is for.
You're out longer than you planned. Traffic, a nap in the car, a friend who wants coffee. Everything else in the bag is insurance against time.
Pack for those two and you can ignore most lists.
The actual contents
Diapers. Twice what you think, which is usually three or four for a short outing.
Wipes, and a second pack. The second pack lives in the car or the stroller and is never touched until the day it saves you.
A change of clothes. Two, under six months. The most-forgotten item and the one whose absence ends the trip.
Something to change them on. A folded muslin or a large swaddle works and doubles as ten other things — a sunshade, a lap cover, a floor for a café.
A bag for the bad thing. Any bag. Its absence is the difference between a mild problem and carrying a soiled item in your hand.
Feeding, whatever that means for you. Bottle and formula, or nothing at all. A bib and a cloth once solids start.
One toy. One. Small, quiet, attached to something if possible. The floor of a café is where toys go to be left behind.
Something for you. Water, and whatever gets you through an unplanned extra hour. This is the item everyone drops and everyone regrets.
Bag or backpack
Backpack, if you're honest. Both hands free is the entire argument, and it wins the moment you're carrying a baby and opening a door.
A shoulder bag is easier to get into one-handed, which matters at a changing table. Some bags do both — handles, a strap, and clips for the stroller — and that's the useful shape: hung on the stroller most of the time, carried when you need it.
Weight matters more than capacity. A big bag gets filled, and then you carry it.
Keeping it packed
Restock it when you get home, not when you leave. The bag is at its emptiest and your memory of what ran out is at its sharpest — this single habit is the difference between a bag that works and a bag that's a lottery.
Once a month, take everything out. You'll find a bib from spring and half a rice cake.
What to leave at home
- The full changing kit. Creams and powders belong where the changes mostly happen.
- Books. Heavy, and they don't get read outside.
- A spare for every eventuality. Shops exist. Almost everything is recoverable.
