Fine motor skills include small muscle movements of the hands and fingers. Examples are picking up a spoon or drawing with a crayon.
Gross motor skills include large muscle movements of the legs and arms. Examples are rolling over and sitting up.
You can help to build an infant’s fine and gross motor skills by doing activities with them. Here are a few activities listed in “The Encyclopedia of Infant and Toddler Activities for Children Birth to 3” Edited by Kathy Charner, Maureen Murphy, and Charlie Clark.
