Therefore, many parents will choose plastic water cups. However, plastic cups also have disadvantages. If plastic cups are used to hold hot water, then the plastic will have some chemical reactions when exposed to high temperature, resulting in some harmful substances. These harmful substances will enter the child’s body together with water, and if it goes on for a long time, the child’s body will be damaged.

2. Glass water cup
The better children’s water cups are made of glass. Glass is a transparent material and does not carry any harmful substances. If there are stains on the cup, it can be clearly seen. In addition, glass cups are easier to clean and disinfect. Although it is better, it is easier to break, so many parents are reluctant to buy it. Especially if the child is naughty, it is easy to break the water cup. Glass has a strong thermal conductivity, and if the cup is filled with hot water, it may scald the child. At present, many glass water cups on the market will have a layer of plastic insulation, which will not burn children. But parents are best not to put too hot water in the cup, because the cup may explode and crack.

It not only does not have the shortcomings of other materials, but also has its own advantages. Therefore, for parents, stainless steel water cups are the best for children. Therefore, many people will prepare a thermos cup for their children in winter. However, because stainless steel contains some trace elements, it should be used with great care.
