When will my baby be able to control her head movement?

First several weeks. Infants can move there heads at birth and over the first 2 months this improves greatly.
Between 2 to 4 month. He will lift the head up a little when prone by one month of age. By 2 month he will be much better. By 4 month there should be a fairly good control of the head. Keep him on his tummy during play time when awake to strengthen those neck muscles!
