Basic introduction

When choosing toys for children, we must pay attention to the physical and mental development and health of infants and toddlers, and the sound emitted by toys should be controlled at less than 70 decibels.

Before the child gets the toy, parents should listen to it by placing it about 30 centimeters away from their head.
