Natural Rubber Soothers: Why Size and Colour Can Change
, by Hello Charlie Blogs, 3 min reading time
If you use natural rubber soothers, you may notice something surprising when you buy a replacement.
The new dummy might look lighter in colour. The teat might seem smaller. Your baby may even notice the difference.
This is common with natural rubber dummies, and it does not usually mean the product has changed size or quality. It is often simply because natural rubber changes with use.
Why does the teat look bigger on the old dummy?
Natural rubber is soft, flexible and made from a natural material.
Over time, sucking can stretch the teat slightly. Some babies suck more strongly than others, so the change can be more noticeable for some families.
Heat, sunlight and incorrect cleaning can also affect natural rubber.
This is why an old dummy may look larger than a new dummy of the same size and brand.
Has the dummy size changed?
Usually, no.
If you have bought the same brand and same age size, the new dummy is usually the correct size. The older dummy has likely changed with use.
This can be confusing, especially if your baby prefers the older, softer dummy.
To reduce rejection, keep a few same-size dummies on rotation rather than letting one dummy become very worn before replacing it.
Why does natural rubber change colour?
Natural rubber can vary in colour from one dummy to another.
It can also darken over time because of exposure to light, air, milk, food oils and regular use.
A colour change does not always mean the dummy is unsafe, but it is a reminder to inspect it carefully.
How often should natural rubber dummies be replaced?
Natural rubber dummies should be replaced regularly.
A practical guide is every 8–12 weeks, or sooner if you notice:
- Cracks
- Stickiness
- Tears
- Excessive swelling
- Weak spots
- Changes in texture
- Any damage from teeth

How to care for natural rubber soothers
Always follow the brand’s care instructions.
In general:
- Inspect before each use.
- Keep out of direct sunlight when not in use.
- Do not clean in the dishwasher unless the brand allows it.
- Do not use harsh chemicals.
- Replace regularly.
- Do not use if damaged, sticky or cracked.
Because natural rubber is softer than silicone, it may wear faster, especially once babies have teeth.
Natural rubber vs silicone dummies
Natural rubber dummies are soft, flexible and often preferred by parents looking for a natural material.
Silicone dummies are usually clearer, more durable and easier to clean, but some babies prefer the softer feel of rubber.
There is no single best choice. It depends on your baby’s preference, your cleaning routine and how often you are happy to replace dummies.
Dummy safety matters
Check dummies regularly and replace them when worn.
Product Safety Australia explains that a mandatory safety standard applies to baby dummies and dummy chains, covering design, construction and labelling.
Never tie a dummy around your baby’s neck, and make sure any dummy clip or chain meets safety standards.
Final thoughts
Natural rubber soothers can change size, colour and texture with use. That is normal for a natural material.
The best way to avoid problems is to rotate a few dummies, care for them properly and replace them regularly.
