Most children are typically able to complete a puzzle of 4-6 pieces around the age of 3 years old. At this age, children are developing cognitive skills, including problem-solving and spatial awareness, which help them manipulate pieces and understand how they fit together. While some children may demonstrate this ability closer to 2 years, particularly those with advanced skills, it generally becomes more common at age 3. By the time children reach 4 years old, they are ready for more complex puzzles with a greater number of pieces and varying shapes, which surpasses the 4-6 piece puzzles mentioned in the question. Thus, the age of 3 is the most accurate and typical milestone for this developmental skill.
