This short-term longitudinal research project was designed to compare the maternal behaviour of mothers whose toddlers had been born preterm with the maternal behaviour of mothers whose toddlers had been born at term ; the outcomes for the toddlers were also assessed. Twenty-one toddlers who had been born preterm with low medical risk (1460-2420 grams) were com pared with 21 term toddlers who were matched in terms of social class. The heightened maternal responsiveness that had been observed during the first year with preterm infants had disappeared by 12 months, and by 20 months it was the mothers whose infants had been born at term who were more vocally responsive. During the second year, the mothers of preterm toddlers were characterised by more maternal control behaviour than were the mothers of term toddlers. Assessments of cognitive and language performance at the gestationally corrected ages of 12 and 20 months did not differentiate the toddlers who had been born preterm and term. In terms of play skills, reflected during interaction with their mothers at 12 and 20 months, the preterm toddlers were more actively involved than were the term toddlers. Despite the successful adjustment of these low-risk preterm toddlers, maternal behaviour was affected by the circumstances of preterm birth, even after 20 months.
