Names that we call if there are multiple babies born in single pregnancy?
There is a fascination with multiple pregnancy
and multiples in our culture and many others. With the rise in the
numbers of multiples, particularly higher order multiples, there are
many questions that are commonly asked.
A multiple birth occurs when more than one fetus is carried to term in a single pregnancy. Different names for multiple births are used, depending on the number of offspring. Common multiples are two and three, known as twins and triplets. These and other multiple births occur to varying degrees in most animal species, although the term is most applicable to placental species.
Multiple birth siblings are either monozygotic or dizygotic. The former result from a single fertilized egg or zygote splitting into two or more embryos, each carrying the same genetic material (genes). Siblings created from one egg are commonly called identical. Since identical multiples share the same genetic material, they are always the same sex. Dizygotic or fraternal multiples instead result from multiple ova being ripened and released in the same menstrual cycle by a woman's ovaries, which are then fertilized to grow into multiples no more genetically alike than ordinary full siblings. Multiples called polyzygotic represent some combination of fraternal and identical siblings. For example, a set of triplets may be composed of identical twins from one egg and a third sibling from a second egg.
The most common form of multiple births for humans is twins. Many placental species give birth to multiples as a matter of course, with the resulting group called a litter.

They are
- one baby - singleton
- two babies - twins
- three babies - triplets
- four babies - quadruplets or quads
- five babies - quintuplets or quints
- six babies - sextuplets

- eight babies - octuplets
- Nine offspring – nonuplets
- Ten offspring – decaplets
- Eleven offspring – undecaplets
- Tweleve offspring – duodecaplets
- Thirteen offspring – tredecaplets
- Fourteen offspring – quattrodecaplets
- Fifteen offspring – quindecaplets
- Sixteen offspring – sexdecaplets
- Seventeen offspring – sepdecaplets
- Eighteen offspring – octdecaplets
- Nineteen offspring – nondecaplets
