The nurse should inform the mother-to-be that she can expect to feel the baby's movements between 16 to 22 weeks of gestation.
At 9 weeks' gestation, the baby in the womb is still very small, measuring only about 0.9 inches (2.5 centimeters) long. While the baby's arms, legs, hands, and feet are beginning to form, the movements are not yet strong enough to be felt by the mother.
The first movements that a mother typically feels are called "quickening" or "fluttering," and these sensations are usually felt between 16 to 22 weeks of gestation, depending on the individual pregnancy. However, some women may not feel movement until as late as 25 weeks of gestation, especially if it is their first pregnancy.
It is important for the mother to be aware of any changes or unusual sensations during the pregnancy and to consult with her healthcare provider if she experiences any concerning symptoms, such as bleeding, cramping, or decreased fetal movement.
