Relocating to Lebanon

My husband and I just put an offer in on a house in Lebanon, close to the square, and the offer was accepted. While we still have a lot of paperwork to go through before we actually have a house - and this house may fall through and we'll have to find another one - it looks like we'll be moving to Lebanon in the new year!

 For me, this both exciting and terrifying. I've lived in Davidson county for over twelve years, after moving here with my family when I was young from West Tennessee. The move will put me out of comfortable reach of a lot of things - family, friends, community, and most importantly my doctors. I've always gone to Vanderbilt, my 10 1/2 month old son has always gone to Vanderbilt, and we're expecting our second child in March! A lot's happening in a little time.

 What do I need to know about the area? (Besides the fact that Targets are sparse unless you want to go to Mt. Juliet) Any suggestions on doctors/hospitals? Where's a good place to get a meal? The house we've put an offer down on currently doesn't have a stove or anything so eating out may be a very real thing for a few days. Where are good places to take my son to play? Are there any groups out there I should be aware of, people to try and meet with?

 Any and all help or suggestions would be greatly appreciated!!
