Final answer:
Identifying hand dominance in toddlers is important for understanding their motor development and brain lateralization.
Step-by-step explanation:
During the toddler stage (ages 1-3 years), it is important to note if a toddler prefers to use one hand over the other as it is a sign of developing hand dominance or handedness. Hand dominance refers to a preference for using one hand more skillfully than the other. Identifying hand dominance in toddlers helps in understanding their motor development and can also suggest possible brain lateralization. It is significant to track hand preference as it can impact their physical and cognitive development.
