Developmental Milestones
Summary
By 9 months of age, infants develop the gross motor abilities of crawling, and can pull themselves up to stand. They also develop the fine motor ability of holding objects with a 3-finger pincer grasp. In terms of cognitive abilities, 9 month old infants turn and orient to their names, and also search for hidden objects due to the development of object permanence.
