I have a park bag filled with sidewalk chalk, balls, little shovels,several types of bubble makers and a spray bottle filled with water for cooling us down, but the 4 year old girl thinks it's the best toy yet. I let the babies go on the climbers as soon as they are brave enough to try but keep a very close eye on them at all times of course. The sooner they experiment with climbers the less fear they will have. But don't get me wrong, I don't take any chances with safety.
