Calling them Irish twins is just an informal way of classifying siblings that are born close together. Some actual twins have different birthdays due to one being born on one day and the other staying in the womb for days or weeks longer.
For the most part, twins and multiples share the same birthday. However, depending on the time of day the babies are born and how long the timespan is between each baby's birth, twins can be born on different days.
The chance that two siblings share a birthday is approximately 1 in 365 = 0.27%. In reality it is slightly more likely than that since birthdays aren't quite evenly distributed and parents may plan to have children around the same time of year but it will be close enough that this is a reasonable starting point.
Birthdays are three times the fun for one Florida family. On Aug. 25, the Lammert family celebrated the birthday of three sisters — Sophia 7, Giuliana, 4, and Mia, 1 — who were incredibly all born on the same day three years apart.
The chance that the third is born on that day as well is 1/365, and assuming that there is no common factor linking those birthdates then the total chance of the three birthdays coinciding is 1/ (365 x 365 ) = 1 in 133000, or 7.5 in 1,000,000.
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.
The Dutch Twins are Kit and Kat, 5 years old and not yet big enough to be called by their real names, Christopher and Katrina. They live in a typical Dutch household, around the turn of the last century. The book follows their day-to-day adventures and accidental mishaps.
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.
While the typical definition of Irish twins is two children spaced 12 or fewer months apart, people do sometimes use the term more loosely to include children born 13, 14, or more months apart, particularly if the children end up in the same grade in school.
Very high-order multiple births
In 1997, the McCaughey septuplets, born in Des Moines, Iowa, became the first septuplets known to survive infancy. Multiple births of as many as eight babies have been born alive, the first surviving set on record goes to the Suleman octuplets, born in 2009 in Bellflower, California.
Funny Riddle Two children are born on the same day from the same mother but they are not twins. How is that possible? They are triplets!
“We were dressed alike but in different colors growing up, so we're going to torture them like that, too.” A local mathematics professor, Olga Malpica Proctor, calculated the odds of twin sisters giving birth on the same day as about one in 12,500 – similar to the odds that someone will be struck by lighting.
The most siblings born on the same day is 5. Catherine (1952), Carol (1953), Charles (1956), Claudia (1961) and Cecilia Cummins (1966) were all born on February 20th. The odds of this happening is about 17.7 billion to one.
February 3rd is the only day where no one in history has ever been born. Despite much scientific study, there is no explanation for this phenomena. Historically it has been referred to as “the empty day” or “nobody's birthday”.
Artificial twinning, false twinning, virtual twinning, and pseudo-twinning are synonymous terms coined to describe the increasingly frequent situation of genetically unrelated children born very close in age (less than eight months apart) to different birthparents being raised as siblings by the same social/legal ...

Monoamniotic-monochorionic Twins
This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords. If you have monoamniotic-monochorionic twins, your healthcare provider will monitor your pregnancy closely.
Such twins, known scientifically as 'MoMo', an abbreviation for monoamniotic-monochorionic, are some of the rarest types of twins, making up less than one percent of all births in the United States, noted the statement. It also stressed that such MoMo twin pregnancies have a high risk of fetal complications.
Half siblings are considered "real siblings" by most because the siblings share some biological relationship through their shared parent. Half siblings can have the same mother and different fathers or the same father and different mothers.
What Is Oldest Child Syndrome? Oldest Child Syndrome is believed by some to be evidence of common characteristics that can be attributed to birth order. These traits of first-born children include a sense of entitlement, responsibility, and ambition.
Fourth born children often develop the ability to deal well with people. This is probably a result of having to deal with all of those personality types growing up. They may also be great thinkers and able to manage challenging situations. They may also become analytical, hard workers and they can be pushy or passive.
