During the first three months of life, most infants will meet the physical milestone of holding their head up. At this stage, babies are developing neck muscle strength and control, which allows them to lift and hold their heads up for short periods while lying on their stomachs or when they are being held. The other milestones, such as sitting up, walking, and running, typically occur much later in infancy and toddlerhood.
