When carrying the baby in her arms, she is seen losing her balance after stepping onto the escalator.
Tragically as she stumbles the boy drops over the side.
His mother appears mortified and rushes down the steps, while the grandmother looks completely devastated, slumped over the side.
Mall staff called paramedics and the boy was rushed to hospital, where he sadly later died, reported People’s Daily China.
The incident occurred in the Wu Yue plaza department store in the Qingpu district of Shanghai.
