At an age when most children are putting their parents through the terrible 2s, Gustav is instead taking on the 5.7m-high walls of the Cardrona superpipe.
His parents, Pete and Bridget, said the super active toddler had a sports box at home, rather than the average toddler's toy box.
He can already ride a bike - without trainer wheels - has his own skateboard, likes to roller-blade around the house, and plays golf.
"He's not a uniquely talented kid or anything," Mrs Legnavsky claims.
She puts Gustav's development and early interest in skiing down to the "interesting lifestyle" the family leads, which gives him opportunities many other children do not have.
Gustav's father is a ski coach and his mother is the manager of a ski field. Link -via Fark
