Most chapters meet monthly. But, you may determine the frequency of your meetings. You're free to schedule your meetings on weekends, nights, or during the day.  It is helpful to keep your target sisterhood members in mind when setting the meeting time.  If you wanting to create a resource to enRICH stay-at-home mom's lives, then often a monthly lunch with a guest speaker may be your best bet.  In that case the kids may just play together while the mom's meet.  With other chapters the goal may be time away from the kids and an evening meeting may be best.
