This is a pretty basic learning toy for toddlers. It teaches shape recognition and hand-eye coordination.
I rounded over most o the points and the pieces are large enough to not be a choking hazard.
One critical consideration is the choice of child-safe paint. Milk paint is a popular choice. In addition to being child-safe, Real Milk Paint adheres particularly well to wood. The paint has a lovely consistency and spreads easily over the project at hand, so you get a beautiful finish on everything from a handmade desk to a farm animal puzzle and all kinds of charming toys in between.(Google)
In this pattern, the shapes are cut separately from the holes. I did this to make the holes a little larger than the shapes. This makes it easier for the toddler to insert the pieces.
