Workshops & Classes 4C's offers workshops and classes on a variety of child care and parenting issues. We offer sessions in English, Spanish and Chinese. To find out about current workshops and classes, see our online calendar or a printable list of upcoming events. Workshop Policy Pre-registration is required for all workshops. In order for a workshop to be offered, we must have a minimum of 10 participants registered by one week before the date of the workshop. If we need to cancel a class due to lack of participants, we will notify those who are registered about the cancellation at least 5 days before the scheduled class date. 4C's may reschedule canceled classes when possible.
