Marginal Cord Insertion Secrets: How It Affects Your Baby’s Health When it comes to pregnancy and childbirth, every detail matters—especially when it involves how the umbilical cord attaches to the placenta. One critical factor is marginal cord insertion, a simple anatomical detail that plays a surprisingly significant role in your baby’s health. Understanding marginal cord insertion can help expectant parents and healthcare providers anticipate potential risks and ensure optimal outcomes. ### What Is Marginal Cord Insertion? Marginal cord insertion occurs when the umbilical cord attaches along or near the edge of the placenta, rather than centrally. Instead of inserting perfectly into the center, the cord attaches close to the placental border—sometimes within 2–3 cm from it. This is one of the most common types of cord attachment, accounting for about 60–70% of all cord placements.
