Infants develop the mouth and tongue control needed to sip from a cup as they begin solids, which typically happens around 6 months. At this age they gain better head and trunk control and improved lip and jaw coordination, allowing small sips from a cup with help. This supports transitioning away from exclusive bottle feeding and promotes oral-motor development as part of weaning. Waiting until 12 or 24 months would miss the normal early introduction window, even though many children progress to independent cup drinking later. So, the best answer is around 6 months.
