WARNING: Download games from trusted website only. I tried my best to see the links are valid and safe, but I dont guarantee anything for it. For buying any cd – check your local toysrus or see best deals online at craiglist,amazon ,ebay or local flea market or gamestop.
You could get your toddler started – with any keyboard banging game.(keep extra keyboard handy). This allows them to get comfortable with computer.
For games we tried Reader rabbit series(but for whatever reasons my daughter did not like it at all)
We finally went to jumpstart series – which are probably the best education games (across pc, wii, dsi). They are available from toddler all the way upto third grade and more.
