We decorated pumpkins.... Love this "Mr. Potato Head" inspired Pumpkin decorating kit. Last year I decided that carving at this age, wasn't all that fun for the wee ones, they just watched for the most part. So while Mom & Dad carve, the kiddos draw on other pumpkins with washable markers. The best part is, you can wipe it all off with water, and do it every day. I think we drew on pumpkins every day leading up until Halloween last year.
Then Mr. Man came home to be attacked by an army dressed in Jammies, lucky for him someone tipped him off and left a spare sword by the door.
