1, the baby's straw cup should be made of PP as soon as possible, because this material is food-grade, which is not only safe, but also harmless to the baby's health. When choosing, you can look at the instructions on the outer packaging of Yin Xue to see if the imported materials are marked. Imported PP materials are more durable than domestic PP materials. In addition, it depends on whether it can be disinfected with boiling water and steam. Some study cups look good, but they are not made of PP. High temperature disinfection will release harmful gases, which is very harmful to the baby's health.
2, to choose a straw cup with the function of causing water leakage, there are many school drinking cups on the market that do not have the function of inverted water leakage, and it is easy for babies to leak water when drinking water or carrying the cups outside. Some enterprises have developed leak-proof learning cups, which will not leak when inverted. Some brands have developed a design that the water cup will not leak when inverted, which is more conducive to the baby's own grip.
