Frequently Asked Questions (FAQ)
Can I wash the insulated cup base inside a steam steriliser?
No. While the individual loose components, straws, and lids are completely safe for standard sterilisers and boiling water, placing the double-wall insulated cup base inside a steam or microwave steriliser is not recommended, as excessive heat can compromise the vacuum insulation seal.
Is the silicone straw tough enough to handle teething toddlers?
Yes. Tommee Tippee manufactures this specific convertible cup with a highly durable, structurally reinforced silicone straw. It is specially designed to remain soft and gentle on sensitive mouths while remaining completely bite-resistant against toddler teeth.
Does the cup leak if my toddler shakes it upside down?
No. Thanks to the advanced anti-leak valve technology, the cup remains entirely leak and shake-proof provided the lid is correctly assembled and either set to the straw mode or rotated fully into the locked padlock position.
Can I use this cup to keep warm milk or hot tea insulated?
No. The 3-in-1 Insulated Cup is strictly engineered for cool, refreshing liquids. Hot beverages should never be added to the cup, as they pose a significant risk of scalding your child, and internal pressure could disrupt the leak-proof performance.
