When can children usually follow a one-step direction without a gesture?

At around 15 months of age, children typically begin to demonstrate the ability to follow simple one-step directions without the need for accompanying gestures. This skill indicates a growing understanding of language, as they start to comprehend verbal instructions without needing visual cues. Children at this stage are developing their ability to process and respond to language more independently, which is a significant developmental milestone in both cognitive and language development. Following one-step directions without gestures reflects their progressing communicative interactions and their ability to understand relationships between words, actions, and objects.
