Summary

The two month developmental milestones refer to a set of abilities that most infants can perform at 2 months of age. In terms of motor abilities, most infants should be able to lift their heads, and use their eyes to track objects across their midline. Socially, infants at 2 months should also develop a social smile, and begin to vocalize by making cooing sounds. The posterior fontanel also closes around 2 months of age.
