It is possible to feel the baby’s head with your fingers, but this sensation occurs when the fetus has descended very low into the pelvis, usually in the later stages of pregnancy or during labor. This physical sign is a direct result of the baby’s position relative to the birth canal. While feeling the head may signal progression, it is important to understand the anatomical context and associated safety considerations before attempting any internal examination.
Understanding Fetal Engagement and Station
The concept of “engagement” describes when the largest part of the baby’s head has successfully passed into the mother’s pelvic inlet. This event is a necessary step before labor can proceed to delivery. For a first-time parent, engagement often happens several weeks before the due date, while for subsequent pregnancies, it may not occur until labor begins.
“Fetal station” is the measurement system used by medical professionals to track the baby’s downward journey through the pelvis. This measurement is calculated by determining the relationship between the lowest part of the baby’s head and the ischial spines. The ischial spines serve as the zero reference point, or Station 0.
Measurements are expressed in centimeters using a range from -5 to +5. Negative numbers, such as Station -3 or -1, indicate the baby’s head is still above the ischial spines and is not yet fully engaged. Positive numbers, such as Station +2 or +4, mean the head has descended past the spines and is moving closer to the vaginal opening. Feeling the baby’s head internally is generally only possible when the fetus is at a positive station, typically +2 or lower.
Identifying the Sensation: What You Might Be Feeling
When the baby is at a very low station, the sensation felt is distinctively hard, round, and smooth, reflecting the bony structure of the fetal skull. The head is noticeably firmer than the surrounding soft tissues of the vaginal wall or the cervix. In some cases, if the membranes are ruptured and the cervix is dilated, it may be possible to discern the sutures or fontanelles.
It is helpful to differentiate this sensation from other tissues. The cervix, for example, typically feels softer, often compared to the tip of the nose or lips. The sensation of the baby’s head is a firm, unyielding mass. Medical professionals advise against frequent internal self-examination, as introducing bacteria can elevate the risk of a serious infection, particularly if the amniotic sac has ruptured.
Safety and Medical Guidance
While feeling the baby’s head can signal labor progression, it is important to treat this finding with caution, especially if the amniotic membranes have ruptured. The most serious risk associated with a low-lying fetal head and ruptured membranes is umbilical cord prolapse. This occurs when the umbilical cord slips down ahead of the baby’s head and into the vagina.
If the cord prolapses, it can become compressed between the baby’s head and the pelvic bone, which can rapidly cut off the oxygen and blood supply to the fetus. The immediate presence of a pulsating cord, which feels like a soft, throbbing structure, is a medical emergency requiring immediate attention. If a pulsating cord is felt after the water has broken, immediately call for emergency medical assistance and assume a position that relieves pressure, such as the knee-chest position.
In the absence of ruptured membranes, feeling the head, particularly when accompanied by intense and regular contractions, is a clear signal to contact the healthcare provider. The provider can then perform a sterile examination to accurately determine the fetal station and cervical dilation. This assessment guides the medical team’s decisions regarding the safety and timing of the delivery.
