Things to do in Nashville, TN with toddlers...?

I may be in Nashville this weekend, I have a 20 month old son. What are some things around for us to do? A children's museum? Does the Opryland Hotel have things for children or does the Opry Mill Mall offer a lot? Thanks in advance...Things to do in Nashville, TN with toddlers...?
