Those more expensive toys are what I'm worried about. S7 is already so enamored of cars that I think he's going to want to immerse himself in expensive undertakings. His older cousins are already involved in race cars (for real) with their dad, and S7 has already said he wants to be a race car driver himself. But at least I can convince a boy he needs to get a job before he begins to think along those lines.
S3, thankfully, just wants to deal with Transformers and Dinosaurs right now.
