Don't buy too many toys for your children, which is not conducive to the development of concentration. My daughter is only 14 months old. She has several boxes of toys and books. She always gives me the picture book. When I read it to her, she gives me another one Immediately.. The same is true when playing with toys. Then she throws books and toys all over the place. Maybe she is too young. I have to control myself not to buy too many things for her in the future.
