Summary

By 12 months of age, infants can stand well and begin to walk. They also begin holding objects with a 2-finger pincer grasp, which requires fine muscle coordination of the index finger and thumb. Socially, 12 month old infants can communicate with nonverbal gestures, like by pointing at objects, as well as begin to say simple words. At 12 months old, infants develop separation anxiety when their caregivers leave. 12 months old is the age at which infants can be introduced to cow’s milk and honey. At 12 months, infants should weigh around triple their birth weight.
