Crying patterns of Korean infants in institutions.

This study investigates whether the crying pattern of infants reared in institutions is different from those reared at home in the same cultural backgrounds. Ninety-five institutional infants and 143 home infants, aged 2-18 weeks were studied through diaries, recorded by children's care-givers or mothers. Results showed that the crying duration of the infants in institutions was almost double that of infants at home (86 vs 45 min/day) and contact period with the care-givers was half that of home infants (136 vs 279 min/day).
