Counting is important (together with keeping track of all possible bonuses). My oldest is 6 and I don't think he's going to play Small World (or Vinci) soon.
Counting isn't a problem. Her Zooloretto and Ingenious skills are frightening.
The worst is when she plays psychologically. "I don't need the giraffe. But I know how much it will torture you if I take it, so I will. Love you anyway, Daddy."
