Lots of good ideas on that link you provided playfelt! I will have to remember to make some for next year.

I have asked the parents to send their costumes in a bag. They will only be wearing them for about an hour My 3.5 year old is to go to preschool in her costume already so that will work out well.

Do you hand out treat bags to your daycare kids before they leave or do they come back in the evening? I normally hand them out at the end of the day because I live on a street where no one hands out and I feel that it's a waste of time for the parents to come here when I have already seen them all day and in their costume.
