Infant fussing and crying patterns in the first year in an urban community in Denmark

Infant crying amounts and patterns in 590 1- to 12-month-old infants in an urban community in Denmark were studied using the Crying Patterns Questionnaire. The impact of the crying on parents and the primary health services was also assessed. The results showed that Danish mothers leave their infants to "cry out" substantially less than mothers in the UK and North America. Despite this difference, mean crying amounts, crying patterns and the incidence of persistent crying were similar to those reported in earlier western studies. The findings support the view that the infant crying peak in the first 3 months is due to normal maturational and developmental processes.
