If you're looking for something new to do you might take the short drive down to Gonzales to visit their beautiful YMCA run Jambalaya park. The park and playground are open to the public and the Olympic size swimming pool can be used by contacting the YMCA. A beautiful open theater area and a gazebo are located in the park. They can be rented out for a nominal fee together or separately.
My sister regularly takes her 2 year old to go play in the kids spraygound. There are fun fountains you can play in. The park is very clean and in a very safe area located right next to City Hall.
