Irish twins is the term for siblings born in the same calendar year or within 12 months of each other.
It is very much possible and I will highlight three cases below starting from the easiest. Case 1: Twins, triplets are the best examples of siblings born on the same year.
The term “Irish twins” refers to siblings who are born within 12 months of one another. This is especially true for children born in the same calendar year, or children who would be in the same grade of school. However, children born within 18 months of one another are still often referred to as Irish Twins.
The term “Irish Twins” refers to siblings born within a year of each other, and it definitely does happen. While birthing two babies in the span of a year has its challenges, there are also many uniquely special benefits to raising siblings close in age.
Twins can be classified into two categories–identical or maternal twins, also known as monozygotic, and fraternal twins, also called dizygotic (1). However, Irish twins refer to siblings born within a year apart and are twin-like.
(Identical twins come from a single fertilized egg that splits in half, while fraternal twins occur when two different eggs are fertilized simultaneously). So, how many months apart are Irish twins? It's technically possible for two siblings to be as close as 9 or 10 months apart.
The Guinness World Records for most children delivered at a single birth to survive is currently held by Nadya Suleman, who gave birth to six boys and two girls in California, US, in 2009. Last month, a 25-year-old Malian woman had given birth to nine babies, two more than doctors had detected during medical scans.
For most women, it's best to wait at least 18 months between giving birth and getting pregnant again. This means your baby will be at least 1½ years old before you get pregnant with another baby. This much time gives your body time to fully recover from your last pregnancy before it's ready for your next pregnancy.
When Sadie Budden spent two years struggling to conceive she thought she might never have children. But then, to everyone's surprise, she gave birth to two – in the space of just six-and-a-half months. Against all the odds, Ronnie and his little sister Sienna were born only 208 days apart.
They are 'mirror-image twins' - a little-known phenomenon that means otherwise identical siblings are asymmetrical in their looks and how they move or interact.
Septuplets (7)
The Frustaci septuplets (born 21 May 1985, in Orange, California) are the first septuplets to be born in the United States. Born at 28 weeks, only two boys and one girl survived; one daughter was stillborn and three died within 19 days of birth.
If you're pregnant with more than one baby, it's called a multiple birth. Two babies are twins and three are triplets. Multiple pregnancies are becoming more common as more women are using fertility treatments and getting pregnant at an older age.
Irish twins are sibling children born within a year of one another to the same parents, but it's an offensive phrase with a troubling background. So Irish twins aren't actually twins at all, they're children close in age, but the results of different pregnancies.
With the help of doctors at CHRISTUS Children's, Valentina gave birth to two baby girls seven months apart. The family's extraordinary journey was nothing short of a miracle.
“There are about 120,000 twin births in the U.S. every year, making up just over 3% of all births. However, twins with different birthdays are rare, and some estimate the chance of twins being born in different years as one in 2 million,” the medical centre added.
Having two babies in the same calendar year is rare, and the colloquial term for it is “Irish twins.” Silas Spencer was born by the C-section at 7:44 a.m. Dec.
Having babies less than a year apart poses risks for both mother and child, whatever the woman's age, according to new research. The authors of a big study of nearly 150,000 pregnancies in Canada say the safest interval between births is 12 to 18 months.
"Births that occur 18 months or less apart have a higher risk of uterine rupture, an emergency situation in which the scar on the uterus opens prior to delivery." That said, while having back-to-back pregnancies isn't usually recommended, it's not always a bad thing.
Superfetation is a rare event that involves getting pregnant a second time while you're already pregnant. It's so uncommon that cases of superfetation often make headlines. Your body does a good job preventing subsequent pregnancies once an embryo is developing inside your uterus.
Research suggests that an age gap of 27 to 32 months may be associated with the best health outcomes for mother and child. In terms of sibling relationship, siblings who are closer in age tend to fight more but are also closer which may have positive benefits for social skills.
A Russian woman named Valentina Vassilyeva is known as being the woman who has given birth to the most children in one lifetime. We often see stories these days about a family that has got anywhere between 15 and 30 children, but nobody comes close to Vassilyeva.
Erramatti Mangamma currently holds the record for being the oldest living mother who gave birth at the age of 73 through in-vitro fertilisation via caesarean section in the city of Hyderabad, India. She delivered twin baby girls, making her also the oldest mother to give birth to twins.
Octuplets are a set of eight offspring born at one birth. An individual that is part of such a set is called an octuplet.
