Charlie loves Legos more than anything. (And it doesn't get any better than Lego Star Wars.) Today we discovered a new thing: nanoblock. The "world's smallest toy building blocks" come in a few architectural landmarks (Eiffel Tower, Taj Mahal) and ridiculously cute animals (panda, giraffe, frog). We took on the Taj Mahal, which turned out adorable and was much less of a commitment—financial and temporal—than the Lego version.
