All of them. Or very nearly so; it's a rare baby indeed that needs to do it twice.
i believe a shark has a baby one at a time.
i think that atleast 4 baby pandas can be born at a time
Bats usually have one live young at a time. Ocassionally, twins are born.
A mother caribou usually has one baby at a time, twins are rare.
Females can have up to 15 cubs.
It is unusual to bear more than one.
A female chimpanzee normally gives birth to just one baby. It is very unsusal for more than one baby per pregnancy.
One chimp baby at each pregnancy is normal. Twins happen, but very rarely.
One baby at a time.
Most large mammals- including the moose- have only one offspring at a time.
Usually one.
because if the horse has two in one belly the horse will die and the baby's will die to.
