Temperature, saliva, sunlight and heat can alter a latex nipple. These changes can cause discolouration and the material can expand and become larger over time. Latex can also become sticky and lose its shape. These are natural stages of the latex aging process.  

An enlarged dummy nipple indicates that it has been in use for some time. This is why the new dummy can appear to be smaller than the old one. 

IMPORTANT INFORMATION

Be aware of natural wear and tear. Natural rubber changes through use and can expand significantly. It is a good idea to regularly check whether the dummy is damaged. Byhappyme recommends replacing dummies approximately every 4-6 weeks. 

You can avoid having one dummy grow significantly larger than the others by having several on the go at the same time. 

Please note that there is significant variation from brand to brand and it is therefore unlikely that the nipple sizes between brands will be identical.   

You are welcome to contact Byhappyme for advice should you wish to change brands or switch to a new material, e.g. from latex to silicone.

All our dummies are 100% BPA, PVC and phthalate-free and comply with the EU EN-1400 standards.
