On average, a pregnant woman will begin to feel the baby kicking at approximately 25 weeks into the pregnancy, according to WebMD. A slight fluttering feeling may be felt as early as 13 weeks.
The point in a woman's pregnancy when she can begin to feel the baby move varies from person to person. If it's the woman's first pregnancy, she may not feel it until close to 25 weeks. For a second pregnancy, movement may be felt as early as 13 weeks. Being still and quiet will make it easier to detect these motions.
Initially, the movement will be very weak and almost unnoticeable. These early fluttering movements are referred to as quickening and are usually infrequent. As the pregnancy progresses, the baby's movements will become stronger and more frequent.
