If at the beginning of the party I give out construction hat, apron, name badge and plastic tools (all from dollar store or oriental trading), total cost less than $5, do I still need to do a goody bag when they leave? I don't want to be stingy, nor do I want to appear too generous (we can afford more things than some friends). I was going to write names on things, so hopefully the kids don't lose anything - but that may cause their own fights too.
