Cultural variation in infant's sleeping arrangements

Morelli, G.A., Rogoff, B., Oppenheim, D., & Goldsmith, D. (1992). Cultural variation in infant's sleeping arrangements: Questions of Independence. Developmental Psychology, Vol. 28, No. 4, 604-613.

Cultural practices differentiate infant sleep arrangements. In the middle-class US population, a common goal is to have infants sleep in their own rooms as soon as possible, consonant with the culture's importance on independence. In the Mayan population, it is not uncommon for children to sleep with their parents or other siblings well on into childhood, reflecting their culture's value on interpersonal relations. Changes are not prescribed by the authors; instead, broader cultural perspective is offered for American readers.
