All great suggestions - can highly recommend Magnatiles and Duplos as well.
Just a word of caution on buying Magnatiles - there are lots of knockoff brands out there, not just for these but almost all kids toys these days (duplos and trains included), and some can be dangerous:
> Last December, Jennifer White of Appleton, Wis., received Imden Magnetic Blocks for her 4-year-old son as a gift. Her son was rushed to the hospital after the toy broke and he ingested some magnets, Ms. White said.
> The worst part? The Imden-branded product was listed right next to industry-leading brands like Magformers and Magnatiles, which meet U.S. safety standards.
