This 3D animation shows a realistic representation of a child developing in her mother's womb. This is a month-by-month guide, seeing a baby's journey from the very beginning at the moment of fertilization, and follow along to her birth 9 months later. We see her bouncing around in the womb at 11 weeks — before her mother can even feel her movements! — and responding to light at 27 weeks. Then, we see her preparing for birth, after which she will gain a whole new set of experiences in the world outside the womb.
