We haven't introduced Levi to Halloween yet. We have Purim as his opportunity to dress up and until he starts public school (or until daycare introduces him to Halloween) we are skipping trick or treating.
I do have a special six year old in my life though, my dear friend's son. I've been teaching him to sew. We've made a pencil case and a cape and he requested a crown to match the cape for Halloween. And if I'm making him one, I figured one for his little brother should be made too. I hope they like them!
