I only know a couple of people who attended WashU back in the day (both loved it), so I don't have any advice. I will say though that it's a gorgeous campus, and I love the fact that it's right next to the Loop and Forest Park. I have family in University City, and the run from their house, through the campus, to the park is one my favorite routes in the country. The dining scene around there is really vibrant too, and I'm sure you and your child will love how friendly everyone is.
