My two-year-old figured out the stacking sequence on her own within a week, and now she narrates "big, bigger, biggest" while she builds. The pieces are smooth with no rough edges, which matters since everything ends up in her mouth. Took a star off only because... no wait, actually I can't find any
The nine pieces are the perfect amount for little hands, and my daughter spends ages lining them up by size before knocking them all down. The cylinders and cones have a nice weight to them, not flimsy at all.
My two-year-old figured out the stacking order faster than I expected, and now she rebuilds the whole thing in about five minutes. The nine pieces are chunky enough for small hands, and she's already lining them up by height without any help.
