I saw on the news this week that Live on the Levee has expanded their children's area. We went a couple of times last year and my preschooler really enjoyed it. The Magic House was there to do crafts, there were inflatable jumping things she loved, and she learned how to hip hop dance. We went with friends and had a great time. We didn't stay for the concerts but it looked like many families did. It sounds like there will now be picnic tables which will be great for dinner.
The best part - it was free!
