My kids are netflix babies and when I gave them a toys r us catalog to look through to pick Christmas gifts out of they looked at it for 2 minutes, threw it aside and didn't ask for anything. Without commercials, they have no sense that they should even want the crap in a toy catalog. Big difference from when I was growing up.
On a serious note, I'm not sure how you managed to pull this off as a parent. Two weeks ago I saw a young child of Asian tourist parents in the streets of Manhattan, standing in front of a major chain drugstore and excitedly flagging down the parents to bring attention to a prominently displayed colorful plastic dump truck placed in the window display, precisely at baby level.
I want to figure out how to keep my future kids from doing that.
