Did you know that when you join SMMC, you can sign up for playgroups and special interest groups to connect with other like-minded parents? We have over 50 subgroups, including age-specific playgroups and groups specific to special interests such as cooking, exercise, cultural groups and special needs. Join one (or more) today!

If you don’t have a playgroup leader, don’t hesitate to post to your playgroup’s forum to see who would like to meet up. You may be surprised at how many responses you get. We also urge you to step up as leader, or talk to another member and initiate co-leadership.
If your playgroup is having trouble getting started, book a few playdates in a spot that you and your child(ren) enjoy. Post all playdates on the subgroup forum. Even if there’s no response, make sure you go—experience has shown us that some people will show up anyway!
Bad weather can often derail playgroup plans. But one way to avoid interruptions—whether it’s too hot or wet for playground slides or the host is sick—is to have a back-up plan in place. You can choose a “bad-weather” spot where you’ll meet so you always have have a Plan B.
Try new parks and spots to meet. This is a wonderful chance to explore all the great places in Marin. We love —it’s a great resource that lists local parks with information on shade, picnic areas, bathroom facilities and types of playground equipment.
