On our visit to St. Louis we went to a very different museum called the City Museum. The boys LOVED it. They had so much fun crawling around, through and all over the place. It is in an old shoe factory that has been converted to a huge playground with all sorts of interesting stuff. A 10 story slide, a school bus that hangs off the roof, a toddler area (that Brady did not like), a mini train ride and all sorts of fun.
