Left-handedness is seen as something unusual. Left-handed children are starting to face difficulties in the family due to different spatial orientation - lateralization. Even more, difficulties await them at school.
In preschool-age, the child refines the motor skills that it already acquired as a baby and thus gains greater independence.
As the basics of body musculature evolves, so does the baby's motor development. With the development itself, they become more diverse and they go from gross to fine.
