I’m a big fan of toys that fold up or stack up neatly, and take up little room in our Manhattan apartment. Of course, if the toy is actually a great toy, well, that’s even better. These new Dado Cubes at Fat Brain Toys fit the bill (and my apartment) nicely. A fresh twist on classic building blocks, Dado Cubes feature slits on each cube which kids can interlock to create an unlimited number of three-dimensional structures. R. and S. are both enjoying them quite a bit (and she helpfully removes the smallest ones from his chubby hands). They look nice, too…very modernist and colorful. At just $24.95, this would be a great birthday gift for kids of just about any age. Visit Fat Brain Toys.
