Reading, Mass. (March 23, 2014) — Some Massachusetts firefighters went the extra mile to make one little girl feel safe.

Four-year-old Kaelyn Kerr, along with her baby brother and mom, got stuck in an elevator after it jammed. The only way to get them out, was up a ladder and over a wall.

Little Kaelyn was too nervous, so to calm her, firefighters serenaded her with the hit song “Let it Go” from the Disney movie “Frozen.”

“It worked, we got her to a point where she was comfortable with us and up the ladder we went, right up and over, no problem” says one of the firefighters.
