A dad came up with a smart hack to get his tot's pram up a flight of stairs without having to unstrap her or carry her.

The funny video shows Mr. Zhang from Wuxi, China smoothly flipping the pram over - allowing his daughter Zhang Youwen to walk up the stairs.

According mum Ms Zhang, there are many bridges and stairs in Wuxi's tourist areas so the dad and daughter duo often cooperate to making each other's life easier.
