Are there any sports or rec department or other similar outside activities available to your child in the current COVID-19 climate...? For example: Swim, dance, tumbling & gymnastics, T-ball? Any places to meet other parents/children in a play group, such as at a church, neighborhood group, park playground, or reading event at a local library?

I ask because it will be important for your family and your child to recognize and emphasize any interests the child may have in common with other classmates or older children they meet.
