A Giant white-tailed rat (Uromys caudimaculatus) usually gives birth to around 2 babies.

Each of those little ones spend around 38 days as a fetus before they are released into the wild. Upon birth, they weight 20 grams (0.04 lbs) and measure 12.9 cm (0′ 6″). They are a member of the Muridae family (genus: Uromys). An adult Giant white-tailed rat grows up to a size of 28.3 cm (1′ 0″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
