At around what age do children typically begin to stack blocks voluntarily?

Children typically begin to stack blocks voluntarily around 15 months of age. At this stage of development, toddlers are improving their fine motor skills and hand-eye coordination, which are essential for manipulating objects like blocks. Stacking blocks requires not only motor skills but also a growing understanding of balance and spatial relationships, which children start to explore around this age.

By 15 months, many children are experimenting with how to fit objects together and are beginning to engage in more complex play activities. While some may start practicing this skill a bit earlier or later, 15 months is generally seen as the average age when this developmental milestone becomes evident. This activity also supports cognitive development as children learn cause and effect through their interactions with the blocks, making it a significant aspect of early childhood growth.
