If you are the architect of your child’s future, and developmental toys are the building blocks, we suggest hiring Manzanita Kids as the contractor.

The Seattle-based venture, launched by David and Adrienne Minnery, turns walnut, cherry, and maple woods into modular building sets, stackers, puzzles, and blocks. The husband-and-wife duo draws upon their backgrounds (his in woodworking, hers in education) to create age-appropriate, ecofriendly, and safe toys for kids.

Our favorite pieces include the building walls and extender kits that let littles construct forts, castles, and underwater seascapes big enough for tushies to plop down in the middle and play. The modular stacking puzzle is designed to teach spatial relations to toddlers, but we think it’s intriguing enough to place on the living room coffee table.

After all, the family that plays together stays together.

Available online at etsy.com, $14-$148.
