Dad's deep voice is more likely to penetrate amniotic fluid and pass it on to the baby, so dad often tells fetal stories to the baby, often sings to the baby and talks to the baby, which will be more conducive to the baby's growth and development, that is, auditory prenatal education or sound prenatal education. Compared with the rigid prenatal education music, it can make the fetus feel happy. In those sleepless nights when children cry, we will magically find that it is easier for children to be quiet when they follow their father and hear his language.
I remember when I was pregnant with my son, we were all very happy. I heard that talking to the stomach often and singing is good for the fetus. So, at that time, my husband used to lie on my stomach and talk to the children, telling him anything interesting every day, for about three months. At that time, children will move, sometimes they will react when chatting with children, and sometimes they will be quiet when they hear their father's voice.
In her early education class, we learned how to do prenatal education interaction for children. When she smiled tenderly, she imitated the way pregnant mothers stroked their stomachs and sang in a particularly gentle voice: "Little tadpoles are black and oily, swaying in the water", without the fierceness when they first entered the door.
