Will it leak?

Under normal use, there should be no concerns about leakage. However, it is recommended for parents to ensure that all parts are in good condition and properly installed. During live broadcasts, it is advisable to avoid putting liquids that are too hot (>50°C) into the cup to prevent a pressure difference between the inside and outside of the cup, which could lead to leakage. If the cup is used by a baby, it is a good practice to remind them to close the lid tightly after drinking to prevent dust, dirt, and spills.

What should I do if my baby does not accept the Weighted Straw Sippy Cup?

A: If your baby does not accept the Weighted Straw Sippy Cup, you can try using a straight sippy cup that does not require biting.

What age range is the Weighted Straw Sippy Cup recommended for?

A: The Weighted Straw Sippy Cup is recommended for babies over 6 months of age.

Will the Weighted Straw Sippy Cup leak if it falls off the dining table or stroller?

A: No, the Weighted Straw Sippy Cup has a 100% leak-proof seal, so it won't leak even if it falls off the dining table or stroller.

Can it be used for milk?

This water cup is primarily designed for babies to drink water. The cup body is made of Tritan material. If it is used for soaking milk for an extended period, the fats in the milk may adhere to the cup body, which can accelerate the aging of the cup material and reduce the product's lifespan when subjected to boiling water sterilization. While it is acceptable for occasional use in emergencies, if you plan to regularly use it for milk, it is recommended to opt for a specialized baby bottle instead.

Is the handle fixed?

This water cup (5oz) features a detachable handle, which makes it convenient for parents to clean it regularly. If you directly hold the handle to pick up the cup without securing the lid tightly, it may cause the cup body to detach and result in damage to the cup. It is recommended to first secure the lid tightly before picking up the water cup.
