“Tween Us” is a feature of the Chicago Tribune and frequently has short, helpful blog pieces about parenting kids 9-12. You can subscribe on their site if you want new posts e-mailed to you. Here are a few I’ve found helpful lately:
“What parents need to know about the Whisper app”
“Scary facts parents need to know about the Tinder app”
and a thoughtful piece asking Why must everything related to kids’ activities be a competition?
