How to fix it
Work through these in order, the most common causes come first.
Start With the Basics
Overpacking: The single most common cause of early zipper failure.
If the zipper needs real force to close, the bag has more in it than the zipper is designed to handle.
Pull tab wear: A frayed or broken fabric pull tab is common on budget bags with plastic hardware and is easily replaced with a loop of cord or a small keyring.
Slider alignment: A zipper that splits open behind the slider as you close it usually means the slider itself has worn wide from repeated stress, not that the teeth are damaged.
Diagnosing Your Specific Problem
Zipper won't close at all, feels jammed: check for fabric caught in the teeth first, then check for overpacking if nothing is visibly snagged.
Zipper closes but reopens behind the slider as you walk: the slider has likely worn wide and needs gentle realignment with pliers, or replacement if severely worn.
Pull tab has broken off or torn away: thread a replacement loop or small keyring through the slider's hole; this is a full fix, not a temporary patch.
Zipper sticks or catches with each use: lubricate the teeth with soap, a candle, or a dedicated zipper lubricant.

FAQ
Common questions
Why do diaper bag zippers break more than other bag zippers?
Diaper bags are overpacked more often than most bags, and are opened and closed multiple times a day, sometimes one-handed while holding a baby, which puts uneven stress on the zipper teeth and pull. Plastic zipper pulls, common on budget bags, also wear faster under this frequency than metal pulls.
Is a broken zipper pull fixable, or do I need a new bag?
A broken or missing zipper pull is usually fixable. A simple loop of strong cord, a paperclip, or a dedicated zipper-pull replacement (sold cheaply online) threaded through the remaining zipper slider hole restores function without replacing the bag.
What causes a zipper to split open instead of closing?
This usually means the zipper slider itself has worn out or become misaligned, often from repeated overpacking that stresses the teeth apart. A slightly bent or worn slider can sometimes be gently squeezed back into alignment with pliers; a severely worn slider typically needs replacement by a tailor or cobbler.
How can I prevent diaper bag zippers from breaking in the first place?
Avoid overpacking past the point w here the zipper has to stretch to close, support the bag's weight with your other hand while zipping rather than pulling the zipper sideways, and choose bags with metal-pull zippers over plastic if you know the bag will see heavy daily use.
