The organization Live Action has put together a beautiful and medically accurate animation of life within the womb, from fertilization to birth. Go to babyolivia.liveaction.org for more resources.


Fertilization
Olivia’s life begins and her gender, ethnicity, hair color, eye color, and other traits are determined.

Week 1
Olivia implants in the lining of her mother’s uterus, where she’ll live for the next 9 months.

Week 3
By week three, Olivia’s heartbeat can be detected, her brain and gastrointestinal tract have begun to form, and the cells for her nerves, blood, and kidney have appeared. Her mother may know of Olivia’s existence through a pregnancy test at this stage.

Week 4
At just four weeks, the buds of Olivia’s arms are and legs are visibly forming, and the right and left hemispheres of her brain are beginning to take shape.

Weeks 5–6
At weeks five and six, Olivia moves spontaneously and reflexively, her bones begin to develop, and her brain activity can be recorded.

Weeks 7–8
Olivia can bring her hands together, she can hiccup, she has had over one million heartbeats, and her ovaries and the cells needed for future generations of children are present.

Weeks 9–10
Olivia’s stage of human development now classifies her as a fetus. She can suck her thumb, swallow, grasp an object, touch her face, sigh, and stretch out in her mother’s womb.

Weeks 11–14
Olivia can play in the womb and her taste buds have matured to discrete tastebuds. By week 14, Olivia’s lips and nose are fully formed, she makes complex facial expressions, and her mother can finally feel her movements.

Weeks 15–16
The neuron multiplication of Olivia’s brain is mostly complete and she is sensitive to touch. At this stage of development, ultrasounds can detect speaking movements in her voice box and her teeth are beginning to grow.

Weeks 19–21
By 19 weeks old, her heart has beaten over 20 million times. At 21 weeks old, Olivia could survive outside of the womb with medical assistance.

Week 27
Olivia can recognize her parents’ voices and will react to sudden loud noises. Her eyes respond to light, and she also has a functioning sense of smell.

Week 38
Olivia exhibits breathing movements, she can produce tears, her umbilical cord is typically twenty to twenty-four inches long, and she will weigh between six and eight pounds at birth.
