Kids used to just go outside, find one another, and play. I see that you are attempting to solve the problem with organizing playdates. However, I think that playdates and structured EVERYTHING for kids is a contributing factor to how we got here.
I think at some point, we need to acknowledge media sensationalism (traditional and social media varieties) have not only poisoned politics and bolstered conspiracy theory popularity, but have vastly overstated the dangers of every day life, making childhood and parenting much worse than a generation or two ago.
