We know playing “Bad Guys” is an integral part of early childhood development — but, as some older kids who are more exposed to the media know, real people can do bad things, too.  We had planned to release a “Bad Guys” episode of Ear Snacks on Valentine’s Day, but first we wanted to explain to you, the parents, how and why we are approaching such a difficult topic, especially in the wake of last week’s tragedy in Parkland, Florida.  This episode is not intended for kids.
