Masquerade

On Purim, children, and some adventurous adults, too, traditionally masquerade—an allusion to G‑d's hand in the Purim miracle, which was disguised by natural events. Make sure your children dress up as good, cheerful characters, such as Mordechai and Esther.

Dress up your kids before taking them to the synagogue for the Megillah reading. Many synagogues have a masquerade party along with prizes for the children during or after the Megillah reading.
