Finding out you’re expecting twins brings a whole new intensity to everything that follows. The excitement, the planning, and the questions all arrive at once. So does the realisation that your pregnancy will be managed quite differently to a single-baby pregnancy.
Connecting early with a complex pregnancy specialist is one of the most important steps for parents of twins. The level and frequency of care needed are genuinely different from those of standard antenatal care.
This guide explains what makes a twin pregnancy medically different, what problems to watch for, and what your check-up schedule and birth planning will likely look like.
Confirming a Twin Pregnancy
Most twin pregnancies are confirmed at the first scan, usually between six and ten weeks. At this early scan, your obstetrician will work out not just how many babies there are, but also how many placentas they share. This detail, called chorionicity, is the single most important piece of information in twin pregnancy care, and it is best worked out in the first trimester.
Twins who each have their own placenta (dichorionic diamniotic, or DCDA) are at lower risk of certain serious problems. Twins who share a placenta (monochorionic diamniotic, or MCDA, or monochorionic monoamniotic, or MCMA) need closer monitoring throughout the pregnancy. For a closer look at how twin types differ, see our guide to identical vs fraternal twins.
Why Are Twin Pregnancies Higher Risk?
A twin pregnancy counts as a high-risk pregnancy in Melbourne because carrying two babies puts a lot more demand on your body. It also creates the chance of problems that simply don’t happen in single-baby pregnancies.
Key reasons for the higher risk:
– Early birth. The most common problem in twin pregnancy. About half of all twin pregnancies are born before 37 weeks. Early birth carries risks for babies’ lung and brain development, depending on how early it occurs.
– Growth restriction. When two babies share the available space, and sometimes a shared placenta, one or both may not grow as well as expected.
– Twin-to-Twin Transfusion Syndrome (TTTS). This only happens in shared-placenta (monochorionic) pregnancies. Abnormal blood vessels in the shared placenta send blood unevenly between twins. This can develop fast and needs specialist treatment.
– Pre-eclampsia. Twin pregnancies carry a higher chance of high blood pressure and pre-eclampsia, partly because of the larger placenta.
– Placenta separating early. The risk of this is higher in twin pregnancies.
– Low iron (anaemia). The extra blood needed for a twin pregnancy means low iron is more common and should be checked.
– Gestational diabetes. The risk is higher than in single-baby pregnancies.
More Checking Is Needed
Carrying twins means more appointments, more scans, and more organised care all through the pregnancy. This isn’t something to feel worried about. It reflects the care that’s genuinely needed to keep both babies well watched.
| Twin Type | Scan Frequency | Starts From |
|---|---|---|
| DCDA (own placenta each) | Every 4 weeks | Around 20 weeks |
| MCDA (shared placenta) | Every 2 weeks | Around 16 weeks |
| MCMA (shared placenta and sac) | Weekly, often with hospital admission | Late third trimester |
For DCDA twins, checking usually involves:
– Growth scans every four weeks from around 20 weeks
– Extra checks on baby wellbeing and blood flow in the third trimester
– More frequent blood pressure and urine checks, given the higher pre-eclampsia risk
For MCDA twins, checking is more intense:
– Scans every two weeks from around 16 weeks
– Specific checks for early signs of Twin-to-Twin Transfusion Syndrome at each visit
– Careful growth and blood flow checks to spot any difference between the twins
Getting experienced maternal-fetal medicine care in Melbourne when problems come up means tricky findings get reviewed by specialists with real depth of skill.
Food and Lifestyle in a Twin Pregnancy
The food and nutrient needs of a twin pregnancy are a lot higher than for a single baby. The general advice is to eat more calories, more protein, and make sure you get enough iron, folate, and calcium. A dietitian who specialises in twin pregnancies can give you advice tailored to you.
Expected weight gain in a twin pregnancy is higher than for one baby, and your obstetrician will watch your progress and set suitable targets based on your weight before pregnancy.
Rest becomes increasingly important in the third trimester as the physical load of carrying two babies grows. Most women find their activity naturally slows down in the third trimester, and that’s completely fine. Listen to your body.
Labour and Birth with Twins
How twins are born depends on chorionicity, the position of each baby, and the course of the pregnancy.
Vaginal birth is possible when the first twin, the one closest to the birth canal, is head-down. If both twins are head-down, or the first is head-down and the second can be managed safely, a vaginal birth may go ahead. Twin births always happen where an operating theatre is close by, in case things change after the first baby arrives.
Planned caesarean is recommended when the first twin isn’t head-down, when serious problems have come up during pregnancy, or when certain shared-placenta setups make it the safer choice. MCMA twins are almost always born by caesarean because of the risk of the cords tangling.
Planned birth timing for twins is usually earlier than for a single baby. DCDA twins are often born around 38 weeks, and MCDA twins around 36 to 37 weeks, depending on how the pregnancy has gone.
The Role of an Experienced Obstetrician
Managing a twin pregnancy takes an obstetrician who is comfortable with complexity, skilled at reading regular scan results, and experienced in managing twin births in different situations.
Dr Steven Hatzikostas is an experienced obstetrician with extensive hands-on experience managing twin pregnancy care. He offers personal private pregnancy care in Melbourne for families expecting multiples, matched to the exact risks tied to each pregnancy’s chorionicity and overall picture.
As a solo practitioner offering 24/7 access to his obstetric patients, Dr Hatzikostas ensures your care remains consistent throughout pregnancy and into the delivery room. For families expecting twins, knowing the same doctor will be there at every stage is genuinely reassuring.
After Birth: Considerations for Twin Families
The weeks after birth with twins are physically and emotionally demanding. Recovering from birth, whether vaginal or caesarean, while also getting feeding sorted for two babies and adjusting to parenthood, is a lot to take on. Structured support after birth, including visits from a midwife or maternal child health nurse, and early help from a lactation consultant if you’re breastfeeding, makes a real difference in these early weeks.
Both babies will have their own newborn check and screening tests before leaving hospital. If either baby was born early or needed care in the special care nursery, extra follow-up appointments will be arranged.
Conclusion
A twin pregnancy needs a higher level of care, a busier check-up schedule, and a specialist team who understands the specific risks involved. The reward for all this extra care is two healthy babies and a family that has been well supported through an extraordinary experience.
Dr Steven Hatzikostas offers experienced, thorough obstetric and antenatal care in Melbourne for twin pregnancies, combining clinical depth with the personal availability that families with complex pregnancies genuinely need. If you’ve just found out you’re expecting twins, booking an early appointment with a specialist is the right first step.
Frequently Asked Questions
Can I just see a GP for my twin pregnancy instead of a specialist?
While shared care with a GP works well for straightforward single-baby pregnancies, twin pregnancies do best with specialist obstetric care all the way through, because of the extra complexity and checking needed. Most obstetricians who manage twin pregnancies recommend being under specialist care from early on.
When do twins usually get born?
DCDA twins are often planned for around 38 weeks. MCDA twins are usually born earlier, around 36 to 37 weeks, and sometimes sooner if complications arise. MCMA twins may be born as early as 32-34 weeks. Timing always depends on the individual pregnancy.
What’s the difference between DCDA and MCDA twins?
DCDA twins each have their own placenta and their own sac. They have a lower risk of placenta-related problems. MCDA twins share a placenta, but each has their own sac. Sharing a placenta creates a risk of problems like Twin-to-Twin Transfusion Syndrome that simply doesn’t happen with DCDA twins.
Do twins always need a caesarean?
No. A vaginal birth is possible for twins when the first twin is head-down, and there are no serious problems. The birth is always managed when an operating theatre is nearby. Your obstetrician will discuss the best delivery method for your situation.
Can I breastfeed twins?
Yes, many women successfully breastfeed twins. Making enough milk for two babies is possible with the right support and frequent feeding in the early weeks. A lactation consultant can give practical guidance suited to feeding twins.
