Children can typically start to zip on their own around the age of 3, assuming someone else has started the zipper for them.
Here's a breakdown of the process:
- Initial Stage (Younger than 3): Children will likely need help with all steps of zipping, including inserting the pin into the box.
- Around 3 Years Old: They can usually manage pulling the zipper up once the pin is correctly inserted. This requires developing the necessary fine motor skills and hand-eye coordination.
- Later Development (Older than 3): With practice, children will become more proficient and eventually be able to manage the entire process, including inserting the pin, aligning the zipper, and pulling it up and down.
It's important to note that every child develops at their own pace. Some children may be ready to zip earlier, while others may take a bit longer. Encouragement and practice are key to helping them master this skill.
