A nurse is assessing a toddler for developmental milestones.At what age should a child be able to build a tower of six cubes?

Choice A rationaleAt 18 months, a toddler is typically able to build a tower of only two to three cubes with coordination and intentional stacking. Building a tower of six cubes requires more developed fine motor skills and spatial reasoning.Choice B rationaleBy 36 months (3 years), most children can build a tower of more than six cubes, often reaching eight or more. This age reflects significant advancements in their fine motor control and hand-eye coordination.Choice C rationaleAt 24 months (2 years), a toddler typically develops the fine motor skills and hand-eye coordination necessary to build a tower of approximately six to seven cubes with relative stability. This milestone is a common indicator of developmental progress in this age range.Choice D rationaleAt 12 months (1 year), most infants are still developing their fine motor skills and are typically only able to stack one or two cubes, often more through trial and error than intentional building of a tall tower. .
