A little more than half of twin pregnancies end in preterm delivery (before 37 weeks). While 40 weeks is the full gestation period of the average pregnancy, most twin pregnancies are delivered at approximately 36 weeks (range 32-38 weeks depending on the type of twin pregnancy).
About one third of all twins are born vaginally and the process is similar to that of giving birth to a single baby. If you're planning a vaginal delivery, it's usually recommended that you have an epidural for pain relief.
The longest interval between the birth of twins is 90 days, in the case of Molly and Benjamin West, dizygotic (fraternal) twins born in Baltimore, Maryland, USA to parents Lesa and David West (all USA) on 1 January and 30 March 1996.
The average length of pregnancy for twins is 36.4 weeks. Babies who are born between 32 weeks and 37 weeks generally do very well. If your babies are born early, they are likely to be fine, but they may need to spend time at the special care baby unit (SCBU) or the neonatal intensive care unit (NICU).
In uncomplicated twin pregnancies, delivery should be considered at 37 weeks of gestation in order to minimize risk of stillbirths and newborn deaths. Where there is only one placenta, delivery should be considered at 36 weeks.
A little more than half of twin pregnancies end in preterm delivery (before 37 weeks). While 40 weeks is the full gestation period of the average pregnancy, most twin pregnancies are delivered at approximately 36 weeks (range 32-38 weeks depending on the type of twin pregnancy).
The most significant percentage of twins (49%) was observed to be delivered at 37-38 weeks, and 6% were preterm. About 60% of mothers were between 25 and 35 years of age, and in 57%, this was their first pregnancy.
For women born 1870-1899, moms of twins averaged reproductive spans of 14 years 11 months versus 14 years for singleton moms. Both results were statistically significant. Moms of twins also were older at the time of their last birth.
Twins not only have a bestie from birth — they also live longer than singletons. And those two factors may be related, according to new University of Washington research.
The Reasons For Early Delivery Include:
risk of infection after premature rupture of the membranes. pre-eclampsia or high blood pressure. pre-existing diabetes or gestational diabetes. genital tract infection (e.g. chlamydia, gonorrhea)
The interval between vaginal delivery of the first and second twins (mean, 21 minutes, range, one to 134 minutes) was 15 minutes or less in 70 (61%) cases and more than 15 minutes in 45 (39%) cases.
Twins Joslyn and Jaxon were born just 30 minutes apart, but have completely different birth years.
In rare cases, fraternal twins can be born from two different fathers in a phenomenon called heteropaternal superfecundation. Although uncommon, rare cases have been documented where a woman is pregnant by two different men at the same time.
You won't necessarily need to have a caesarean section if you're expecting twins. Many women expecting twins have a vaginal birth. Talk to your midwife and obstetrician about your circumstances, and the birth options open to you. It's natural to feel nervous about vaginal birth if you're expecting twins.
You may have heard that being pregnant with twins means an automatic C-section, but that isn't always the case. When it comes to twins these days, about half come into the world vaginally.
Having two babies at a time is associated with a longer life, according to a new study. But that's not because doubling up on dirty diapers increases life span; instead, moms of twins are physically stronger in the first place.
In addition, previous studies have shown that first-born twins are, on average, taller and heavier than second-born twins until adolescence (Silventoinen et al., 2007; Pietiläinen et al., 2002).
Monoamniotic-monochorionic Twins
These types of twins share a chorion, placenta, and an amniotic sac. This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords.
This is why fraternal twins run in families. However, only women ovulate. So, the mother's genes control this and the fathers don't. This is why having a background of twins in the family matters only if it is on the mother's side.
Milk supply works on the principle of supply and demand. Breastfeeding tells a mother's body to produce more milk in response to her baby's (or babies') needs. With two babies, more milk is removed from the breasts, so more milk is made.
It is estimated that 1 in 250 natural pregnancies will naturally result in twins. While twin pregnancies can happen by chance, there are some factors that may increase your odds of having two babies at the same time. Let's learn about twins!
The American College of Obstetricians and Gynecologists (ACOG), for example, recommends delivery between 34 and 37 weeks for twins with a shared placenta and at 38 weeks for twins with separate placentas. Some other physician groups recommend delivery closer to 39 weeks with separate placentas.
These standard charts may not describe optimal weight gain patterns because recommended delivery gestational age for twins is between 37 and 42 weeks with average twin birth weights ≥2500 g to reduce mortality and morbidity.
Expect the whole procedure to take a few hours. Maybe two or three, with a few hours on either side for check ups and aftercare.
