The INF Kits are our small kits, but at 3
children aren't really ready to build very sophisticated things. At
this age, children inspect the individual pieces, ponder the shapes and
fit them together, and like to show them to other people or bang them
together. What is important is for children to learn some of the names
of the shapes, and eventually, to learn to stack one piece on top
another (an important milestone). This set will be adequate for 6
to 9 months, but after that will need to be supplemented by
more pieces. Our blocks are too large to pose a choking hazard and
are laboratory tested to satisfy the CPSC rules for children over the
age of three. The blocks are sanded maple, and children can gum them
without fear of chemical finishes or oils.
