Hi Sam, we met a few couples traveling the world with young children. One of our friends even gave birth in Thailand and after a short break, just kept traveling. When you speak to their children, even though they're young, you sense a real difference. Anyway, just wanted to say that people do still do this. Here's a blog of the aforementioned friend: http://almostfearless.com/ (update: she's expecting a second and is currently in Lebanon).
