What age is best to start wooden toys?

Reviewers generally introduce wooden rattles and teethers from around 3 months, simple bead mazes and grasping toys around 6–12 months, shape sorters and chunky peg puzzles from 12–18 months, and classic block sets from age 2+. The Melissa & Doug 100-block set, for example, is labeled 2+ and verified-purchase reviewers on Target and Walmart confirm that's about right for productive stacking play.
