Quintuplets

Quintuplets are the birth of five "twin" babies at the same time; due to this, it is rare feat to birth five healthy babies.

History
Addison delivered quintuplets in Much too Much. Quintuplets are often born small and premature, due to the womb's incapibility to hold too many babies at one. And such for the quintuplets, complications can arise quite easily.

The list of baby births by number goes as such:

Singleton (most common, a single birth, boy or girl)

Twins (fraternal boy/girl, girl/girl, boy/boy, or identical girl/girl, boy/boy)

Triplets (identical or fraternal)

Quadruplets (identical or fraternal)

Quintuplets (identical or fraternal)

Sextuplets (identical or fraternal)

Septuplets (identical or fraternal)

Octuplets (this is the highest pregnancy birth on record, so far.)

NOTE: As the quintuplets and above begin rising higher in numbers, identical births become less and less common.
