REGARDLESS OF STERILIZER USED, this is how often you should change your bottles and teats:
- Bottle teats: 3 months
- PP bottles: 3 months (PP material does not take high temperatures well, thus it tends to yellow)
- PPSU bottles: 6 months to 12 months (PPSU is of a higher quality plastic which withstands UV sterilisation well)
Signs to replace baby bottles and teats:
- Any signs of damage on teat like cracks or tears etc.
- For glass bottles, if you notice any scratches, cracks, leaks and chips.
