The capacity of children's water bottles should be selected according to the age of the child and the amount of drinking water. Generally speaking, children aged 3-5 need to drink about 1000 ml of water per day, and children aged 6-12 need to drink about 1500 ml of water per day. Therefore, it is recommended to use a cup of about 300ml for children under 3 years old, which is more suitable in terms of weight and capacity. Children older than 3 years old should use a cup with a large capacity of about 500ml.
If you are a kindergarten child, you must choose a straw to avoid choking caused by direct drinking; if you are in a lower grade of primary school, you can choose a straw and direct drinking, and if you are older, you can choose to use a cup lid and direct drinking. The advantage of the lid is that the temperature of the hot water can be higher, so that the heat preservation time is longer, and the child can pour the water into the lid to cool down before drinking.
Children's thermos cups are often placed in schoolbags or carried alone. Children will inevitably run and jump when walking, so their airtightness must be good to prevent water from flowing out and scalding children.
Children's thermos cups are inevitably bumped, so they must be resistant to falling, so the material is preferably stronger stainless steel, and the glass material is not suitable for children in terms of safety.
