A Collared pika (Ochotona collaris) usually gives birth to around 3 babies.With 2 litters per year, that sums up to a yearly offspring of 6 babies.

Upon birth, they weight 8 grams (0.02 lbs) and measure 5.1 cm (0′ 3″). They are a member of the Ochotonidae family (genus: Ochotona). An adult Collared pika grows up to a size of 18.8 cm (0′ 8″).

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″).

The collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha which comprises rabbits, hares, and pikas. It is a small (~160 gram) alpine lagomorph that lives in boulder fields of central and southern Alaska (U.S.), and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. It is closely related to the American pika (O. princeps), but it is a monotypic form containing no other recognized subspecies. It is asocial, does not hibernate, and spends a large part of its time in the summer collecting vegetation that is stored under rocks (“haypiles”) as a supply of food for the winter. Some individuals have been observed collecting and consuming dead birds as sources of fat and protein. Thousands of trips are made during July and August to collect vegetation for winter.
