The first perception of a baby’s movements, known as quickening, is a significant milestone in pregnancy. Quickening is the initial recognition of fetal activity, marking the transition to a tangible, felt reality. Although the fetus begins moving around the 12th week of gestation, these motions are too subtle to be detected by the mother. The timing of quickening varies widely, but for those who have been pregnant before, this event typically occurs much sooner.
What Quickening Feels Like
The sensations of quickening are often subtle and can easily be mistaken for common digestive activity, especially early on. Initial fetal movements are frequently described as a gentle flutter, similar to butterfly wings or a tiny fish swimming. Other reports include sensations resembling the bubbling of gas or a light tapping against the abdominal wall.
These soft, fleeting movements are distinct from the stronger kicks, jabs, and rolls typical in later pregnancy. They are frequently felt low in the abdomen, near the pubic bone, because the uterus is still low in the pelvis. As the pregnancy progresses, the movements become more definite and easier to distinguish from other internal sensations.
Why Subsequent Pregnancies Feel Movement Sooner
A person experiencing a third pregnancy (multigravida) typically feels quickening much earlier than a first-time mother (primigravida). A first-time mother may notice movement between 18 and 22 weeks of gestation, while a multigravida often perceives it between 13 and 16 weeks. This difference is due to physical changes and maternal experience.
The abdominal and uterine muscles of a multigravida are less rigid, having been stretched by previous pregnancies. This increased elasticity makes it easier for subtle early movements to transmit and be felt. Furthermore, an experienced mother immediately recognizes the unique sensation of quickening. While a first-time mother might mistake early flutters for indigestion, an experienced mother is more attuned and recognizes the movement sooner.
Other Factors Influencing Fetal Movement Timing
Several physical variables influence when quickening is first perceived, beyond the number of previous pregnancies.
Placenta Location
The location of the placenta plays a significant role in how movement is felt. An anterior placenta, attached to the front wall of the uterus, acts as a cushion between the fetus and the abdomen. This placement can dampen the force of early movements, potentially delaying the perception of quickening.
Maternal Body Mass Index and Activity
Maternal Body Mass Index (BMI) also affects timing; a higher BMI may lead to a later perception of movement due to extra abdominal cushioning. Conversely, individuals with a lower BMI may report feeling movements sooner. Additionally, movements are most often noticed when the mother is resting quietly, allowing her to focus on internal sensations.
Tracking Movements After Quickening
After quickening occurs, the focus shifts to recognizing the pattern of fetal movement, which indicates fetal well-being. Although early flutters are sporadic, they will become more regular and noticeable. Healthcare providers typically recommend beginning formal monitoring, often called “kick counts,” around the 28th week of pregnancy.
The American College of Obstetricians and Gynecologists (ACOG) suggests timing how long it takes to feel 10 movements, including kicks, flutters, or rolls. Ideally, 10 movements should be felt within a two-hour period. If a significant deviation from the baby’s established pattern is noticed, such as a marked decrease in movement, immediate contact with a healthcare provider is warranted.
