WHEN three children are born to a woman at the same time, we call them triplets and when there are four quadruplets.
Decaplets are very rare - that is when 10 children are born at the same time! But it has happened - three times! The most recent case was in Brazil in 1946.
Most often, when that many children are born at the same time, some are too weak to survive. -
