If you have kids those are three words that put fear into your heart. But never fear, I've collected a bunch of ideas of things to do with my kids, and you can try them too. The YMCA offers a host of programs from swimming classes and soccer, to camp and day care settings. Every branch offers different programs. JCC offers several one week camps, and units of two week camps for ages 18 months through 8th grade.
Swimming is done in a lot of camps, including instructional swim.
Louisville Parent also offers a directory of local and non-local camps. The library is doing their annual summer reading program. If your child reads 10 books they receive a gift package of small toys and coupons to many local places that kids enjoy. There is a free kick off Saturday, June 5th at the Speed Art Museum. They also offer a story time at many locations.
