By the end of pregnancy, the baby's eyes will turn in the orbit and will actively practice opening and closing their eyes!
However, the fetus has vision in the womb. Their eyesight is blurred, but sometimes they react to bright light sources (such as sunlight) or light that suddenly flashes across their mother's abdomen.
Staying outdoors often contributes to the development of fetal eyes and reduces the risk of eye diseases. When the mother is sunbathing, the baby will feel the stimulation of strong light and see red light.
Fetal hearing begins to develop from about 3 months of pregnancy. The inner ear structure of most fetuses is formed at 16 weeks, and sounds can be heard from this time. At the 24th week, the cochlea, eardrum, ossicles and other important ear structures were fully formed. After that, the fetus can easily hear the mother's heartbeat, breathing, walking, exercising, burping and digestive peristalsis.
By the second trimester, they can respond to external stimuli. The sound transmission effect of amniotic fluid in the uterus is good, but the sound that the fetus hears may be similar to that we hear in the water.
When the fetus is 24 weeks old, it can already distinguish different sounds from the outside world and the inside of the mother, so pregnant mothers should talk to the baby as much as possible and pat the baby's stomach as much as possible. It would be better if some beautiful music could be played, and the fetus could move with the rhythm of the music.
Usually, the fetus's hearing will become acute in 32-35 weeks, when he will turn his head to a certain sound source. The most attractive thing to the fetus is the mother's voice, so the newborn can hear the mother's voice from everyone!
