Designing a wooden toy for kids aged 9 to 17 months needs to be very safe, with materials and edges that won't easily get damaged. The toy should be easy for kids to use on their own.

To make it interesting, the toy should move in some way and have colors or shapes that catch kids' eyes. It can be inspired by nature, like animals or plants, to make it more fun and educational.

It should also help kids learn and grow physically by giving them feedback when they play with it. This way, playing with the toy helps kids develop and learn new skills.
