When did your children start really playing games? We have candyland, but ds (turned 3 in August) doesn't really get the concept. He gets that you move to a color, but he doesn't understnad the going forward part and he just goes anywhere. I 'm not to excited about introducing the idea of a "winner" to him, so . . .
I was thinking of buying Haba Orchard for Christmas, but if he won't understand it for a while, I might put it off for a while.
when his older brother was about 5 he loved any board game. We made him board games for Christmas one year with dragons and knights. He also loved Jenga, and connect 4.
