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.
Multiples are generally born only a few minutes apart. If delivered by cesarian section, the interval between births is usually only a minute, maybe two. The interval is generally longer for vaginal deliveries, ranging from a few minutes to more than an hour.
Medically, this 7-year defect is very rare. Twins are typically born with a bit of a delay — a few minutes to a few hours.
born years apart but still so eerily similar: KITTY DIMBLEBY's son and daughter were born three years apart but conceived at exactly the same time. Nine-year-old Chloe was clearly teacher, while six-year-old Max was — along with the teddies — one of her students.
As Maria Jones-Elliott hugs her two babies, she hails them as “little miracles”. For twins Amy and Katie were incredibly born 87 days apart. Maria went into labour four months early, giving birth to Amy – but Katie did not arrive until three months later.

A pair of twins were set to be delivered in Texas just around midnight on New Year's Day — and ended up being born in separate years. Kali Jo Scott gave birth to her first twin baby girl Annie Jo at 11:55 p.m. on Dec. 31 and then delivered the second daughter, Effie Rose, at 12:01 a.m. on Jan.
Twins with different birthdays are rare, and the chance of twins being born in different years is 1 in 2 million, according to the news release by Natividad. Though the incident is rare, it's not the first time twins have been born in separate years.
When people refer to Irish twins, it's important to recognize that although the siblings are close in age, they are not actually twins. In other words, they were not born during the same gestational period. Calling them Irish twins is just an informal way of classifying siblings that are born close together.
Yes, it is possible to have twins with different biological fathers. The scientific term for this anomaly is “heteropaternal superfecundation,” and it's super cool.
(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.
Despite their seven-year age gap, the three siblings are officially considered triplets. This is because they were conceived at the same time, using the same batch of eggs and sperm.
The longest recorded human pregnancy was 375 days, or just over 12 and a half months, according to Guinness World Records. During this pregnancy, a woman named Beulah Hunter gave birth to a healthy baby girl in 1945.
Yes, you read that right. Twins (non-identical) can be born at completely different times, sometimes even years apart.
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.
Therefore, children with a spacing of less than 12 months became known as Irish twins (also known as “Catholic twins” or “Dutch twins”).
Pseudo-twins can form in ordered structures under high stress conditions. These twins are defined by lattice sites that are at twin positions but are incorrectly occupied by different species of atoms.

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.
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.
Homopaternal superfecundation is fertilization of two separate ova from the same father, leading to fraternal twins, while heteropaternal superfecundation is a form of atypical twinning where, genetically, the twins are half siblings – sharing the same mother, but with different fathers.
Kali and Cliff Scott's twin daughters were born on two different days, Dec. 31, 2022, and Jan. 1, 2023. Scott and her husband Cliff, who are from Denton, Texas, were expecting their daughters to arrive on Jan.
"We demonstrate that by the 14th week of gestation twin fetuses do not only display movements directed towards the uterine wall and self-directed movements, but also movements specifically aimed at the co-twin, the proportion of which increases between the 14th and 18th gestational week," the scientists stated.
Not many twins can say they have different birthdays, and even fewer can say they have different birth years. There is about a one in 2 million chance that twins will be born in different years, but newborn twins Annie Jo Scott and Effie Rose Scott joined this ultra-rare club on New Year's Eve.
