Another thing that was a bigger hit than I thought it would be (no pun intended!) was the baseball shaped pinata. The children LOVED this! I was a little reluctant to have a bunch of 4 year olds swinging bats at a pinata, even if they were plastic ones. Jonathan really wanted one, so I gave in, and with adult supervision, all went well.
They were each given a baseball printed bag to gather their loot. I found candy on the lawn for weeks after!
