I really wish folks were more careful about the videos they post of their kids. Infrequent clips of activities like singing in a choir or playing a sport are one thing, but increasingly I see videos of small people (kids are in fact people) having meltdowns, or crying (even from happy overwhelm), or otherwise being vulnerable. Consider that if you took videos of your friends while they were crying, then posted them, you'd be an unsafe person for them to hang out with.
Be your kid's safe person.
