Protective Sleeping It matters little what infants sleep in—bassinet, cradle, crib, or Billum bag made from local plants in Papua, New Guinea, as shown here. In fact, this kind of bag is very useful since babies can easily be carried in it. It can also be used for carrying food, tools, and much else. What does matter is the infant’s sleeping position—always on the back, like this healthy infant.
