To compare the social competence, motor development, and cognition of late preterm infants (LPIs) with full-term infants

Gross and fine motor skills were significant associated with social skills. Late preterm infants were at risk of motor developmental delays

To examine longitudinal patterns of early development in Canadian children born late preterm

At 4 and 8 months of age late preterm infants had significant lower scores at gross motor skills than the full-term infants. At 4 months of age late preterm infant had lower score at fine motor scales that the full tern infants. There were no significant differences at the age of 18 months between groups

The aim of this study was to compare the risk of developmental delay between late preterm and full-term Canadian born infants at age 12 months, and to determine infant and maternal factors associated with risk of delay

Late preterm infants were at risk of motor developmental delays at the age of 12 months

To compare the effects of a short bout of practice on reaching behavior between late preterm and full-term infants at the onset of goal-directed reaching

Late preterm infants had great variability of proximal of reaching after practice and exhibited smaller variability for distal adjustments. Late preterm infants had less beneficial from this practice program
