It's really troublesome. My children can't be idle, and my mother is a little overwhelmed when she is old. Later, my friend recommended me to buy a morning education machine for my children called Niu Ting. It not only tells stories, but also has many small expressions. It's cute, and the baby likes it. It is also very convenient. I must take it with me when I go for a walk in the park. Look at its function, there are 50w+ selected resources, from nursery rhymes to songs. It's inexpensive and cost-effective.
