My 5 yr old son is getting into legos. Frustrating as hell. As soon as you get the bat copter/ mario motorcycle, etc built, they try to play with it like a normal toy. So it pretty much gets demolished within the first 5 min of play, the kid gets upset, and there you are back building the stupid thing again. Legos for little ones are evil and I am convinced that they are designed to ultimately cause discontent.
