**1. Introduction**

It is known that multiple pregnancy presents morbidity and mortality rates about 3–7 times greater than single pregnancies, and these are often determined in delivery care [1].

Among the difficulties in twin birth, we highlight: prematurity, non-cephalic presentations, dystocia, funicular prolapse, placental abruption, increased operative incidence, postpartum hemorrhages, perinatal anoxia and tocotraumatism [2].

In this chapter we will review the main aspects related to the time and mode of delivery in multiple pregnancies and issues related to fetal weight assessment.
