The video was filmed by the boy’s mother at a wildlife park in in the Glen Waverley area of Melbourne, Australia when he tries to feed a kangaroo .
It shows the hesitant boy approaching the country’s iconic animal under the supervision of his dad.
The man encourages him: “Walk straight at it, just walk straight at it.”
As it does so it appears to headbutt or graze the kangaroo which then fires a stiff left jab that lands on the oncoming child’s face.
A small scream from someone watching the incident can be heard on the recording before a brief family inquiry into what happened.
