Poster of lockdown song in kindergarten classroom will break your heart

Since more than 20 school shootings have taken place in 2018 so far, educators are taking serious measures to teach students what to do in the event of an active shooter or other emergencies on campus. It's 2018 and kids in kindergarten are learning letters, numbers, shapes, and how to survive school shootings.

And while it's extremely important to inform children on safety precautions, this poster of a lockdown song hanging in a kindergarten classroom will absolutely break your heart.

On Wednesday, Georgy Cohen, the mother of a child who will be entering kindergarten in the coming school year, shared a gut-wrenching photo of the classroom she visited.

A poster, seen hanging on the chalkboard, has lyrics to a song about classroom lockdowns largely written in colorful markers. "This should not be hanging in my soon-to-be kindergarteners' classroom," she wrote.

Here are the lyrics:

The tweet gained a lot of traction, sparking a conversation about school safety and the harsh realities of gun violence. Many were also upset that this is an issue children have to start worrying about at just five years old.

Cohen also revealed in the thread that her child had already been taught lockdown drills in pre-kindergarten classes.

Since posting, Cohen's tweet has gained more than 25,000 likes and 12,000 retweets. And in place of the usual self-promotion following a tweet going viral, the mom simply requested that people call their congressional representatives to advocate for gun reform or support organizations like Everytown and Sandy Hook Promise.
