Ask your mother who used early education in love and music. What is the effect after using it?
The effect is not good, especially when I was told that I could listen 24 hours at first. As a result, the baby became more and more agitated and couldn't sleep well. I didn't feel so bad after listening to it, but I still couldn't sleep well. Later, I changed my sleep album in the complete collection of Alpha brainwave music recommended by others, and finally I adjusted it.
