Adults shouting at children can be as harmful to a child’s development as sexual or physical abuse, study finds [cnn.com]

Several of Advancing Parenting's bumper stickers address this issue.

12. Support children's healthy development by never telling them they're stupid, ugly, good-for-nothing, worthless, etc.

16. Support children's healthy development by not making derogatory remarks about them to other people while in their presence.

21. Protecting children from physical, sexual, verbal, and psychological abuse supports their healthy development.

23. Support children's healthy development by avoiding words like these, “You’re just like your no-good jailbird cousin!”

31. Speaking quietly and teaching children to speak quietly supports their healthy development.

44. Support children's healthy development by not fighting or arguing with your partner in front of them, if it’s the kind of thing that would frighten the average child.

And people love them!

At stoplights you can use your rearview mirror to watch drivers and passengers read the message.  They point, smile, nod, and conversations begin.  Often a phone is used to take a picture of the bumper sticker right at the stoplight! Presumably, the photos are being shared on social media.  People seem pleased that parenting information is being shared in this very public way.
