This video is stating how a fetus can sense a mother's psychological state. We all know that a fetus can feel the mother's heartbeat inside the womb and we all know that the fetus can hear it's mother's voice and/or other sounds surrounding it. What we might not have known about a fetus and a mother is that whatever the mother is feeling, the fetus can also feel and can be dangerous for the fetus when born. If a mother is depressed and/or unhealthy, the fetus can sense that feeling and when born can be unhealthy and depressed also. The baby can have neurological problems and psychiatric disorders. This is a reason why it is very important for a mother to be as healthy as possible while pregnant.
