Many families have been asking this question. All in all, we encourage you to budget your exposure risks with the balance necessary to maintain mental health. If having playdates, we recommend finding a family that is taking similar precautions to your family, keep the play dates out of doors, encourage safe distance (6 feet) in between children and masking is always encouraged if children are older than the age of two years old.
As a side bar, many families ask about the safety of playground structures. Thankfully, data shows that the majority of transmission of COVID is through direct person to person contact and not through hard surfaces. If going to a playground, schedule it for a time when it is likely to be less crowded, bring hand sanitizer to wash your child's hands before and after playing, encourage them not to touch their face while playing and be ready to abort! if you feel uncomfortable.
