Kangaroos produce two kinds of milk under adverse conditions

In unfavorable conditions,female kangaroos can pause their pregnancies.When that happens, she's able to produce two different kinds of milk,one for her newborn,and one for her older joey.The word mammalia means of the breast,which is a bit of a misnomer because while kangaroos do produce milk from nipples in their pouches,they don't actually have breasts.
