What this dot point is asking
CCEA wants you to know roughly how a baby develops during the nine months of pregnancy, why antenatal (before-birth) care matters, the main checks and tests carried out, and what antenatal classes offer. This topic links the healthy lifestyle of the previous topics to the care given once pregnancy is confirmed.
How the baby develops in pregnancy
Development is often described in three stages of about three months each:
- In the first three months, the fertilised egg implants and the main organs, the spine, the brain and the heart begin to form. By the end the baby (now a fetus) is recognisable, with limbs, fingers and a beating heart.
- In the middle three months, the baby grows quickly, the mother usually feels it move, and details such as hair, nails and eyebrows develop.
- In the final three months, the baby gains weight and fat, the lungs mature, and it usually settles head-down ready for birth.
Why antenatal care matters
A woman sees a midwife and sometimes a doctor regularly through pregnancy, with appointments becoming more frequent towards the end. Catching a problem such as high blood pressure early can prevent it becoming dangerous, which is why these routine checks matter even when everything feels fine.
Antenatal checks and tests
At appointments the midwife typically:
- measures blood pressure (high blood pressure can signal pre-eclampsia),
- tests the urine for protein (another sign of pre-eclampsia) and sugar (which can indicate gestational diabetes),
- weighs the mother and measures the bump to track the baby's growth,
- listens to the baby's heartbeat, and
- arranges blood tests (for example to check blood group and iron levels) and ultrasound scans.
Antenatal classes
Antenatal classes are sessions for expectant parents, usually later in pregnancy. They explain what happens during labour and birth, teach breathing and relaxation techniques and pain-relief options, and cover the basics of caring for a newborn such as feeding and bathing. They also let parents meet others expecting babies at the same time.
Examples in context
- Example 1. Spotting pre-eclampsia early
- At a routine appointment a woman's blood pressure is raised and there is protein in her urine. The midwife arranges extra monitoring, catching possible pre-eclampsia early so it can be managed. This shows exactly why routine antenatal checks matter, the point CCEA wants you to explain.
- Example 2. A scan confirming the due date
- An ultrasound scan measures the baby and confirms the due date, while also checking the baby is growing well and lying in a healthy position. This illustrates the purpose of scans in antenatal care.
- Example 3. Learning at antenatal classes
- First-time parents attend antenatal classes, learning breathing techniques for labour, the pain-relief options available, and how to bath and feed a newborn. They feel far less anxious, showing how classes prepare parents for both the birth and early parenthood.

CCEA Unit 1 style6 marksExplain why antenatal care is important during pregnancy.Show worked answer →
Up to six marks for explained reasons (roughly one mark per point with development).
Antenatal care monitors the health of the mother: blood pressure, weight and urine are checked to spot problems such as pre-eclampsia early.
It monitors the baby's growth and wellbeing: the midwife checks the baby's size, position and heartbeat, and ultrasound scans check development and the due date.
It detects and manages problems early: tests can pick up conditions in the mother or baby so they can be treated.
It gives advice and reassurance: parents learn about diet, lifestyle and what to expect, which reduces worry.
Markers reward several explained reasons covering the mother, the baby, detecting problems and giving advice.
CCEA Unit 1 style4 marksDescribe two checks or tests that are carried out at an antenatal appointment.Show worked answer →
Two marks per check for naming it and saying what it is for, up to four marks.
Blood pressure is measured to check for high blood pressure, which can be a sign of pre-eclampsia, a condition dangerous to mother and baby.
A urine test checks for protein (another sign of pre-eclampsia) and sugar (which can indicate gestational diabetes).
Other acceptable checks: weighing the mother, measuring the bump to track the baby's growth, listening to the baby's heartbeat, blood tests, and ultrasound scans. Each must be linked to its purpose.
