For safety and hygiene reasons, it is international practice to replace baby products such as silicone nipples and replacement seals every 3 months and the other plastic parts such as feeding bottles, collars and storage lids every 6 months or if there are any signs of wear and tear.
However, as our products are designed to grow with your child, you may convert your feeding bottles into snack or semi-solid cups to store purees and soup stock. Superb for the weaning phase and food prep, we say!
