A nursery school in the US has turned its emergency lockdown drill into a rhyme so youngsters know what to do if there is a shooting.
The instructions, written to the tune of Twinkle, Twinkle, Little Star, was taped to a board in a Massachusetts kindergarten class.
An image of the poem telling children what to do in the event of a shooting was posted by a troubled parent who spotted it as she toured her child's prospective nursery in Somerville, a city northwest of Boston.
:: US school shootings: a deadly history
Georgy Cohen, from Massachusetts, said in her tweet: "This should not be hanging in my soon-to-be-kindergartner's classroom."
Thousands of people liked and commented on Ms Cohen's post, with many expressing concern and sadness at the song having to be displayed at the school.
Responding, Ms Cohen said: "The school is doing exactly what they need to be doing, and I am glad for it.
"My issue is with the political & cultural factors that brought us to this sad state. Please talk to your legislators about the need for gun reform."
The superintendent of Somerville Public Schools said lockdown drills were a sad necessity, adding that "unfortunately this is the world we live in".
Im only going to add one more comment to this: the school is doing exactly what they need to be doing, and I am glad for it. My issue is with the political & cultural factors that brought us to this sad state. Please talk to your legislators about the need for gun reform.

The song reads:
Lockdown, Lockdown
Lock the door
Shut the lights off
Say no more
Go behind the desk and hide
Wait until it's safe inside
Lockdown, Lockdown
It's all done
Now it's time to have some fun!
