Thanks to ever-advancing ultrasound technology, we can see babies in the womb in astonishing detail like never before. This not only leads to improved quality of care for mothers, but it also shows whether babies are properly developing. Moreover, it highlights quite clearly that what is in the womb is a tiny, growing human being.

At just 3 1/2 weeks after fertilization, a heartbeat can be heard. At six weeks, hands and feet are seen developing. At seven weeks, the child can be seen sucking her thumb, stretching, and even sighing.
