How Often Should You Replace Baby Bottles? Signs It’s Time to Change

Parents often ask how often baby bottles should be changed. There is no single replacement schedule for every bottle because material, usage, washing method and wear all matter.

Replace a bottle if it is cracked or chipped

Any crack, chip or structural damage is a clear reason to stop using the bottle.

Check for cloudiness, staining and odour

Plastic bottles can show wear over time. Persistent odours, heavy staining or surface deterioration are signs to reassess the bottle.

Inspect threads and seals

If collars no longer tighten correctly or a bottle starts leaking despite correct assembly, inspect the threads and components.

Glass bottles

Glass bottles should be inspected carefully for chips, cracks or impact damage before use.

Teats usually need replacement more often

Soft feeding components can wear faster than the bottle body. Always inspect teats for stretching, splits, stickiness or damage.

For choosing a replacement, see our baby bottles in Kenya guide and bottle size guide.

Frequently asked questions

Do baby bottle teats need replacing before the bottle?
Often yes. Soft teats can show wear earlier than the bottle body, so inspect them regularly.

Should I replace bottles on a fixed schedule?
Condition matters more than a universal timetable. Follow the manufacturer's care instructions.

Can scratched bottles still be used?
Deep scratching or damaged surfaces are a reason to consider replacement.
