Here in Australia, we have what is called "the baby bonus" (a payment from the Australian government.) This article is about a different kind of "baby bonus." http://www.clarionledger.com/articl...livers-rare-set-quads?gcheck=1&nclick_check=1
I was surprised to learn that these babies are an identical set of quads (meaning that the egg split into 4.) They are not 2 sets of identical twins (which can come about if a woman releases 2 eggs at the same time.)
