First things first...

Get a 3-ring binder and page protectors. Start saving all of your contracts, notes, ideas, brochures, business cards, quotes, sample menus, questions, and potential guest lists... Make sure you have the correct Hebrew spellings for your child's name, mother's & father's names, and grandparents too (if child's mother & father are called up for an aliyah). Anyone else who may be called up to the Torah for an aliyah will also need to know their Hebrew name (and their parents' Hebrew names.) Save invitations that you and/or your child receive, for reference. Save a copy of your synagogue's bulletin/newsletter so you will be able to easily write the announcement for your own child. Save a program from a Bar or Bat Mitzvah at your synagogue to become familiar with the variety of aliyot (honors) that might be available for you to assign to your family members and/or friends.Keep a copy of your child's Torah reading or other important information.
