Since your husband will be working downtown and you will only be staying here for a year, the Uptown area would be a great place to live. Lots of restaurants, close to the zoo and Louisiana Children's Museum.
My former neighbors take their daughter to Kidopolis and LOVE it. Albeit, he is a doctor at Tulane and she is a nurse at Tulane. But from what I heard, it is definitely the best in the area. We would have chosen to take our 19 month old there but it was too out of the way.
We ended up choosing KinderHaus Montessori. It's expensive but we liked all the teachers, the set up, and the teaching style.
