My nephew is 7 and he loves money! He also likes football (shirts, jerseys, etc.), Spiderman, and Yu-Gi-Yoh (sp?) cards.
When he was 3, he was into Tonka-type trucks and plastic tool sets, as JenB suggested. At 3, he should still be into the Barney, VeggieTales and Blue's Clues video stage.
so, do we think some legos maybe for the 7 year old, a veggie tale movie for the 3 year old and maybe a dvd set for the 45 year old?
