Understanding the stages of pregnancy can be an exciting and enlightening journey. At eight months pregnant, a lot of developments have occurred, and the baby has grown significantly. However, there is often confusion regarding the terminology used to refer to the baby during this stage. This article will clarify what the baby is called at eight months pregnant, detailing the development, medical terminology, and common terms used by expectant parents and healthcare professionals.
The Medical Term: Fetus
At eight months pregnant, the baby is medically referred to as a fetus. This term is used from the end of the embryonic stage, around eight weeks of pregnancy, until birth. The word “fetus” is derived from Latin, meaning “offspring” or “young one.” The fetus has undergone significant development by this stage, and the term is used universally in medical and scientific contexts to describe the baby in the womb.
Fetal Development at Eight Months
Physical Growth and Maturity
At eight months, the fetus is approximately 16.5 to 18 inches long and weighs around 4 to 6 pounds. The baby’s body is becoming more proportionate, with a noticeable increase in body fat. This fat helps regulate body temperature after birth. The skin, which was previously translucent, becomes more opaque as fat accumulates underneath.
Lung Development
One of the most critical developments during the eighth month is the maturation of the lungs. The lungs are producing surfactant, a substance that keeps the air sacs in the lungs from collapsing and helps the baby breathe after birth. Although the lungs are not fully mature, they are capable of functioning with medical assistance if the baby is born prematurely.
Brain and Central Nervous System
The brain continues to develop rapidly during this month, with significant growth in the cerebral cortex. This part of the brain is responsible for processing information, memory, and conscious thought. The central nervous system is also maturing, improving the baby’s ability to control body temperature and movement.
Movements and Activity
The fetus is very active at eight months, with noticeable movements that can sometimes be seen from the outside. These movements are essential for muscle development and joint flexibility. The baby can open and close its eyes, suck its thumb, and respond to stimuli such as light, sound, and touch.
Positioning for Birth
By the eighth month, the fetus usually moves into a head-down position in preparation for birth. This position, known as the vertex position, is the most common and preferred position for delivery. However, some babies may still be in a breech position (feet or buttocks down) or transverse position (sideways). If the baby is not head-down, healthcare providers may discuss options for repositioning the baby or planning for a cesarean delivery.

Common Terms Used by Parents and Caregivers
Baby
Despite the medical terminology, many expectant parents and caregivers simply refer to the fetus as the “baby.” This term is universally understood and emphasizes the personal and emotional connection parents have with their unborn child. Using the term “baby” can make the pregnancy feel more real and foster bonding.
Little One
“Little one” is another affectionate term used by parents. This term highlights the small, delicate nature of the unborn child and conveys a sense of endearment and protection. It is a common term used in conversations, pregnancy books, and parenting forums.
Bump
Some parents refer to their unborn child as the “bump.” This term originates from the visible baby bump that appears as the pregnancy progresses. It is a playful and light-hearted way to talk about the baby without using medical terminology.
Nickname
Many parents choose a nickname for their baby during pregnancy. These nicknames can be based on the baby’s expected name, personality traits, or simply be a fun or whimsical term. Common examples include “Peanut,” “Bean,” “Nugget,” or “Bun” (as in “bun in the oven”). Nicknames can create a sense of individuality for the baby even before birth.
Understanding Medical Terminology
Embryo vs. Fetus
It is essential to distinguish between the terms “embryo” and “fetus.” The term “embryo” is used from the moment of fertilization until the end of the eighth week of pregnancy. During this period, the primary structures and organs are forming. After the eighth week, the term “fetus” is used to describe the developing baby until birth. This distinction helps healthcare providers communicate accurately about the stages of development.
Gestational Age
Gestational age is a term used to describe the age of the pregnancy from the first day of the last menstrual period (LMP). At eight months pregnant, the gestational age is typically around 32 to 36 weeks. Understanding gestational age is crucial for tracking the baby’s development and planning for birth.
Trimester System
Pregnancy is divided into three trimesters:
First Trimester: Weeks 1 to 12
Second Trimester: Weeks 13 to 26
Third Trimester: Weeks 27 to 40
At eight months pregnant, the mother is in the third trimester. This period is characterized by rapid fetal growth, increased maternal discomfort, and preparation for childbirth.
The Emotional Connection
Bonding with the Unborn Baby
Bonding with the baby during pregnancy is a natural and important process. Many parents find that referring to the fetus as their “baby” or using a nickname helps strengthen this emotional connection. Talking to the baby, playing music, and feeling the movements are all ways to enhance bonding.
Preparing for Parenthood
As the due date approaches, parents often begin preparing for the baby’s arrival. This preparation includes setting up the nursery, purchasing baby clothes and supplies, and attending childbirth classes. Using personal terms like “baby” or “little one” during this time can make the preparation feel more immediate and meaningful.
The Role of Ultrasound
Seeing the Baby
Ultrasound technology allows parents to see their baby in the womb. During the eighth month, ultrasound images can show detailed features, including the baby’s face, hands, and feet. These images often solidify the baby’s identity for the parents and make the pregnancy feel more real.
Checking Development
Ultrasound is also used to monitor the baby’s development and position. Healthcare providers can check the baby’s growth, amniotic fluid levels, and the placenta’s health. These check-ups provide reassurance to parents and ensure the baby is developing as expected.
Health and Safety Considerations
Prenatal Care
Regular prenatal care is crucial during the eighth month of pregnancy. These appointments allow healthcare providers to monitor the mother’s health, check the baby’s development, and address any concerns. Common tests during this stage include measuring the baby’s growth, listening to the heartbeat, and monitoring blood pressure.
Nutrition and Hydration
Maintaining a healthy diet and staying hydrated are essential for both the mother and the baby. Adequate nutrition supports fetal growth and prepares the mother’s body for childbirth. It is important to eat a balanced diet rich in vitamins, minerals, and protein.
Rest and Comfort
As the pregnancy progresses, the mother may experience increased fatigue and discomfort. Resting and finding comfortable positions can help alleviate some of these symptoms. Supportive pillows and proper sleep hygiene are beneficial.
Recognizing Preterm Labor
At eight months pregnant, it is crucial to recognize the signs of preterm labor. Symptoms include regular contractions, lower back pain, pelvic pressure, and changes in vaginal discharge. If any of these signs occur, it is important to contact a healthcare provider immediately.
Conclusion
At eight months pregnant, the baby is medically referred to as a fetus, but many parents use terms like “baby,” “little one,” or a nickname to describe their unborn child. This stage of pregnancy is characterized by significant development in the baby’s body, brain, and lungs. Bonding with the baby, preparing for parenthood, and maintaining good prenatal care are essential during this time. Understanding the terminology and developments at eight months can help expectant parents feel more connected and prepared for the arrival of their new family member.
