Multiple babies born at the same time are commonly referred to as "multiples." This term typically includes twins (two babies), triplets (three babies), quadruplets (four babies), and so on. These births can occur naturally or through assisted reproductive technologies. The term "multiple births" encompasses all instances of more than one baby being born during a single pregnancy.

The largest number of single births to one woman without any multiple births is 69. This record is held by the wife of Feodor Vassilyev, a peasant from Shuya, Russia, who gave birth to 69 children in the 18th century.
Multiple births can sometimes be predicted based on certain factors such as genetics, maternal age, and the use of fertility treatments, which increase the likelihood of twins or higher-order multiples. However, it is not possible to accurately predict multiple births in every case. Ultrasound and other medical assessments can confirm multiple pregnancies once they occur, but prior indicators are not definitive. Overall, while some factors can suggest a higher likelihood, the exact occurrence of multiple births remains uncertain until confirmed by medical imaging.
